How to Find Length of String in Java, Python, C++, Javascript, SQL, Shell script, Mysql, Oracle, and Perl

How To Find Length Of String in Java, Python, C++, Javascript, SQL, Shell script, Mysql, Oracle, and Perl: This article will offer you advanced knowledge of various computer languages. Strings are groups of characters that will represent a single word or an entire phase. It will summarise how to find the length of a string in Java, how to find the length of string in Python, how to find the length of a string in C++, how to find the length of the string in Javascript, how to find the length of the string in SQL, how to find length of string in Shellscript, how to find the length of the string in MySQL, how to find length of string in oracle, how to find the length of the string in Perl.

How to Find the Length of the String in Java?

The length of a string is calculated with the total number of characters it contains. Hence, to calculate the length of a string in Java, the in-built length method Java script class can be initiated. Moreover, in Java, strings are objects produced using the string class, and the length method is referred to as the public member method of the class. Therefore, any variable of type string can access the type string method through the.(dot )operation

In Java, you can find the length of a string using the length() method. Here’s how you can do it:

public class Main {
    public static void main(String[] args) {
        String myString = "Hello, World!";
        int length = myString.length(); // This gives the length of the string
        System.out.println("Length of the string: " + length);
    }
}

The length() method is a built-in function of the String class in Java. It returns the number of characters in the string, including spaces, punctuation, and any special characters.

In the example above, the output will be:

Length of the string: 13

So, the length of the string “Hello, World!” is 13 characters.

How to Find the Length of the String in Python?

Strings are simple to use in Python as they don’t have any explicit declaration ad can be defined with or without a specifier. However, python has a variety of in-built functions and methods for manipulating as well as accessing strings. Hence, Everything in Python is an object, a string is an object of string class which has several methods.

Example

In the program given below, we are taking a string as an input, and by using the len() function we are finding out the length of that string.

s1 ="Tutorialspoint"

length =len(s1)print("The Length of the string",s1,"is",length)

Output

The output of the above program is,

('The Length of the string', 'Tutorialspoint', 'is', 14)

How to Find the Length of the String in C++?

There are five different ways to calculate string length in C++. In C++, we can include traditional character array strings and C++ has String Class. We can calculate string length through different methods.

For C++ strings, using the length() or size() member functions is more convenient and safer, as they handle various complexities such as memory management and null termination automatically. For C-style strings, using strlen() or loop-based approaches is common, as they are more suited for character arrays with null-terminated strings.

Example

#include <iostream>
#include <string>

int main() {
    std::string myString = "Hello, World!";
    int length1 = myString.length(); // Using length() function
    int length2 = myString.size();   // Using size() function

    std::cout << "Length of the string using length(): " << length1 << std::endl;
    std::cout << "Length of the string using size(): " << length2 << std::endl;

    return 0;
}

Output

csharpCopy codeLength of the string using length(): 13
Length of the string using size(): 13

Both length() and size() functions give you the same result, which is the number of characters in the string, including spaces, punctuation, and any special characters. You can use either of them based on your preference.

How to Find the Length of the String In Javascript?

In JavaScript, you can find the length of a string using the length property of the string object, which returns the number of characters in the string. For example,

javascriptCopy codeconst myString = "Hello, World!";
const length = myString.length;

console.log("Length of the string: " + length);

Output

cCopy codeLength of the string: 13

How to Find Length of String in SQL?

Using LEN() function (for Microsoft SQL Server): If you are using Microsoft SQL Server, you can use the LEN() function instead of LENGTH().

SELECT LEN('Hello, World!') AS length;

Output:

markdownCopy codelength
-------
13

Both LENGTH() and LEN() functions return the number of characters in the specified string. The result represents the length of the string, including spaces, punctuation, and any special characters.

How to Find the Length of String in Shellscript?

In shell scripts, the length of the string can be calculated by the built-in shell parameter expansion feature or by using the expr command. Here are two common methods to find the length of a string in a shell script:

1. Using Shell Parameter Expansion: You can use the ${#variable} syntax to get the length of a string stored in a variable.

bashCopy code#!/bin/bash

myString="Hello, World!"
length=${#myString}

echo "Length of the string: $length"

Output

cCopy codeLength of the string: 13

2. Using expr the command: The expr a command is used for evaluating expressions in shell scripts. You can use it to find the length of a string as follows:

bashCopy code#!/bin/bash

myString="Hello, World!"
length=$(expr length "$myString")

echo "Length of the string: $length"

Output

cCopy codeLength of the string: 13

Both methods will give you the length of the string, including spaces and special characters. You can apply any approach based on your preference and the complexity of the task you are performing in your shell script

How to Find the Length of String in Mysql?

You can use the LENGTH() function in various scenarios, such as in SELECT queries, WHERE clauses, or in combination with other SQL functions to perform different operations on strings.

SELECT LENGTH('Hello, World!') AS length;

Output

markdownCopy codelength
-------
13

In the above example, the LENGTH() the function is applied to the string 'Hello, World!', and it returns 13, which is the length of the string.

How to Find the Length of String in Oracle?

To calculate the length of the string in Oracle, Choose LENGTH() to count bytes and CHAR_LENGTH() to count characters based on your needs.

Using LENGTH() function:

sqlCopy codeSELECT LENGTH('Hello, World!') AS length FROM DUAL;

Using CHAR_LENGTH() function:

sqlCopy codeSELECT CHAR_LENGTH('Hello, World!') AS length FROM DUAL;

Both queries will give the output:

markdownCopy codeLENGTH
------
13

How to Find the Length of String in Perl?

The Perl code to find the length of a string:

perlCopy codemy $length = length("Hello, world!");
print "Length: $length\n";

When you run this shorter Perl script, it will produce the same output:

makefileCopy codeLength: 13

This version removes the intermediate variable and directly prints the length of the string using the length() function.
