Convert Input string into Uppercase  There are many built-in classes in the Java programming language. ' String ', ' Scanner ', ' Math '   are some of out of all the built-in classes inside the Java programming language. And here you need ' String ' class to convert the input string into Uppercase which is present inside the ' lang '   package of the ' java ' project. All the built-in classes in Java contain many methods which are helpful to perform the mentioned specific task. So to convert the inputted string into uppercase you need to call  toUpperCase() method from the String class. And is done by the keyword called  ' import '. import   java . lang . String ; //Importing String class from lang package import  java . util . Scanner ; //Importing Scanner class from util package public  class StringToUC {      public static void main(String []args)     {           String ...
