Example Application: calculator
x + y
Example
System.out.println(String.format("%.2f + %.2f = %.2f", x, y, x + y));
x - y
Example
System.out.println(String.format("%.2f - %.2f = %.2f", x, y, x - y));
x * y
Example
System.out.println(String.format("%.2f * %.2f = %.2f", x, y, x * y));
x / y
Example
System.out.println(String.format("%.2f / %.2f = %.2f", x, y, x / y));
