Run the following code to check how String class Methods work, discuss with tutor, if you need explanation of any method. Make changes and try different variations. String myString ="KOI is my University";
String s1= "KOI";
String s2= "koi";
String s3 = " Hello KOI ";
System. out. println("Char at index 2(third char): " + myString. charAt(2)); System. out. println("After Concat: "+ myString. concat("-Enjoy-")); System. out. println("Checking equals with case: " +s2.equals(s1)); System. out. println("Checking Length: "+ myString. length()); System. out. println("Replace function: "+ myString. replace("fun", "easy")); System. out. println("SubString of myString: "+ myString. substring(8)); System. out. println("SubString of myString: "+ myString. substring(8, 12)); System. out. println("Converting to lower case: "+ myString. toLowerCase()); System. out. println("Converting to upper case: "+ myString. toUpperCase()); System. out. println("Triming string: " + s3.trim()); System. out. println("searching s1 in myString: " + myString. contains(s1)); System. out. println("searching s2 in myString: " + myString. contains(s2));
