Answer 1

$\textbf{\large Program}$

   $\texttt{public class SwapValues \{}\\\\\texttt{\hspace{1.5em} int a, b;}\\\\\texttt{\hspace{1.5em} void swapper() \{}\\\texttt{\hspace{3em} int temp = a;}\\\texttt{\hspace{3em} a = b;}\\\texttt{\hspace{3em} b = temp;}\\\texttt{\hspace{1.5em} \}}\\\\\texttt{\hspace{1.5em} void show() \{}\\\texttt{\hspace{3em} System.out.println("A - " + a);}\\\texttt{\hspace{3em} System.out.println("B - " + b);}\\\texttt{\hspace{1.5em} \}}$

           $\texttt{public static void main(String[] args) \{}\\\texttt{\hspace{1.5em} SwapValue obj = new SwapValue();}\\\texttt{\hspace{1.5em} obj.show();}\\\texttt{\hspace{1.5em} obj.swapper();}\\\texttt{\hspace{1.5em} obj.show();}\\\texttt{\}}$

   $\texttt{\}}$
