How to search a word inside a string?

Here is the example that 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 SearchStringEmployee{
   public static void main(String[] args) {
      String strOrig = "Hello all employees";
      int intIndex = strOrig.indexOf("Hello");
      
      if(intIndex == - 1) {
         System.out.println("Hello not found");
      } else {
         System.out.println("Found Hello at index " + intIndex);
      }
   }
}

Output

Found Hello at index 0

Here we can see, Whether a word exist within a String object.

public class HelloWorldExample {
   public static void main(String[] args) {
      String text = "The mouse is on the Chair";
      System.out.print("Text Exist : "+text.contains("the"));
   }
}

Output

Text Exist : true
