Below is an example of the length () method, which will help determine the length of a string.

import java.io.*;
public class Test {

   public static void main(String args[]) {
      String Str1 = new String("Welcome to wikitechy.com");
      String Str2 = new String("Tutorials" );

      System.out.print("String Length :" );
      System.out.println(Str1.length());

      System.out.print("String Length :" );

   }
}

String Length :24
String Length :9

Also, using the length () method, you can not only learn the length of a string, but also compare the length of a string. Below is an example of how this can be done.

public class Example {  
public static void main(String[] args)  
  {    
    String str = "wikitechy.com";  
    // Get the length of str.  
int len = str.length();  
System.out.println();  
System.out.println("The string length of '"+str+"' is: "+len);  
System.out.println();  
   }  
}
