Java String length() Method (original) (raw)

Last Updated : 23 Dec, 2024

**String length() method in Java returns the length of the string. In this article, we will see how to find the length of a string using the String length() method.

**Example:

Java `

class Geeks { public static void main(String[] args){

    String s1 = "abcd";
    System.out.println(s1.length());

    String s2 = "";
    System.out.println(s2.length());

    String s3 = "a";
    System.out.println(s3.length());
}

}

`

**Important Points:

• The length() method returns the number of characters present in the string.
• Suitable for string objects but not for arrays.
• Can also be used for StringBuilder and StringBuffer classes.
• It is a public member method.
• Any object of the String class, StringBuilder class, and StringBuffer class can access the length() method using the ****( . )** dot operator.

public int **length()

**Return Type: The return type of the length() method is **int.

Examples of Java String length() Method

1. Use of length() method to find size of String

Java `

public class Geeks { public static void main(String[] args){

    // Here str is a string object
    String str = "GeeksforGeeks";

    System.out.println(str.length());
}

}

`

Output

The size of the String is 13

**2. Compare the size of two Strings

Java `

// whether the length of two strings is // equal or not using the length() method import java.io.*;

class Geeks { public static void main(String[] args) {

    String s1 = "abc";
    String s2 = "xyz";

    // storing the length of both the
    // strings in int variables
    int len1 = s1.length();
    int len2 = s2.length();

    // checking whether the length of
    // the strings is equal or not
    if (len1 == len2) {
        System.out.println("The length of both the strings"+ " are equal and is "+ len1);
    }
    else {
        System.out.println("The length of both the strings"+ " are not equal");
    }
}

}

`

Output

The length of both the strings are equal and is 3
