import java.util.Scanner;

Scanner scan = new Scanner (System.in);
String x = scan.nextLine();
x = x.toUpperCase();
System.out.println (x);

}

Correct one.

Answer 2

toUpperCase

It is a method not a keyword.
There should be pranthesis after this.

x.toUpperCase();

// return x.toUpperCase;
x = x.toUpperCase();

Answer 5

We can't return from a method having void return type.

And the other thing., program stop executing the block of code in which return encountered at that line.

Therefore, in this just convert string to uppercase.
