Java Examples - Search in a String


Problem Description:

How to search a word inside a string ?


This example shows how we can search a word within a String object using indexOf() method which returns a position index of a word within the string if found. Otherwise it returns -1.

public class SearchStringEmp{
   public static void main(String[] args) {
      String strOrig = "Hello readers";
      int intIndex = strOrig.indexOf("Hello");
      if(intIndex == - 1){
         System.out.println("Hello not found");
         System.out.println("Found Hello at index "
         + intIndex);


The above code sample will produce the following result.

Found Hello at index 0
