Java - String startsWith() Method


This method has two variants and tests if a string starts with the specified prefix beginning a specified index or by default at the beginning.


Here is the syntax of this method:

public boolean startsWith(String prefix, int toffset)


public boolean startsWith(String prefix)


Here is the detail of parameters:

  • prefix -- the prefix to be matched.
  • toffset -- where to begin looking in the string.

Return Value :

  • It returns true if the character sequence represented by the argument is a prefix of the character sequence represented by this string; false otherwise.


import java.io.*;

public class Test{
   public static void main(String args[]){
      String Str = new String("Welcome to Dineshonjava.com");

      System.out.print("Return Value :" );
      System.out.println(Str.startsWith("Welcome") );

      System.out.print("Return Value :" );
      System.out.println(Str.startsWith("Dinesh") );

      System.out.print("Return Value :" );
      System.out.println(Str.startsWith("Dineshon", 11) );

This produces following result:

Return Value :true
Return Value :false
Return Value :true
