subString(..) method is used to fetch a chunk of letters from a String.
Say, if we want to get the String "llo" from "Hello".
Also, we want to get the String "el" from "Hello".
public class Test{
public static void main(String[] arg){
String firstString = "Hello";
String subStr1 = firstString.subString(2);
String subStr2 = firstString.subString(1,2);
System.out.println("The subString is : "+subStr1);
System.out.println("The subString is : "+subStr2);
}
}
