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 ="Is NSW Lockdown really over!"; String s1= "NSW"; String s2= "nsw"; String s3 = " Welcome to NSW "; System.out.println("Char at index 2(third char): " + myString.charAt(2)); System.out.println("After Concat: "+ myString.concat("-for sure-")); System.out.println("Checking equals with case: " +s2.equals(s1)); System.out.println("Checking Length: "+ myString.length()); System.out.println("Replace function: "+ myString.replace("Is", "was")); 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));
