How to tell that one string contains another string

This problem is a little simple, isn't it? The last one also used the Stream stream, so this question was directly given points? Don't doubt yourself, just use the contains () method of the string class.

Public class StringContainsSubstring {public static void main (String [] args) {String S1 = "Silent King II"; String S2 = "Silence"; System.out.println (s1.contains (S2));}}

The output is as follows:

True

The indexOf () method is actually called inside the contains () method:

Public boolean contains (CharSequence s) {return indexOf (s.toString ()) > = 0;} Thank you for reading this article carefully.
