Search for substring

//The program below searches through a string and checks for a substring
public class SearchlastString {
   public static void main(String[] args) {
      String strOrig = "Hello world ,Hello Reader";
      int lastIndex = strOrig.lastIndexOf("Hello");

      if(lastIndex == - 1){
         System.out.println("Hello not found");
      } else {
         System.out.println("Last occurrence of Hello is at index "+ lastIndex);
      }
   }
}

//Alternatively you could do the same thing with the help of strOrig.lastIndexOf(Stringname)

public class HelloWorld{
   public static void main(String []args) {
      String t1 = "Tutorialspoint";
      int index = t1.lastIndexOf("p");
      System.out.println(index);
   }
}
