How to check if a string contains a substring Java

Question

Hi Team,

I have two Strings, str1 and str2. How do I check if str2 is contained within str1?

Hi@akhtar,

The first and foremost way to check for the presence of a substring is the .contains() method. It's provided by the String class itself and is very efficient. The method accepts a CharSequence and returns true if the sequence is present in the String we call the method on.

String string = "Java";
String substring = "va";
System.out.println(string.contains(substring));

Hope this helps!
