public static void main(String[] args) {
double a = Double.parseDouble(args[0]);
double b = Double.parseDouble(args[1]);
double sum = a + b;
double prod = a * b;
double quot = a / b;
double rem = a % b;

System.out.println(a + " + " + b + " = " + sum);
System.out.println(a + " * " + b + " = " + prod);
System.out.println(a + " / " + b + " = " + quot);
System.out.println(a + " % " + b + " = " + rem);

System.out.println();
System.out.println("sin(pi/2) = " + Math.sin(Math.PI/2));
System.out.println("log(e) = " + Math.log(Math.E));
}

The out put is

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at Ex3.main(Ex3.java:21)

Process completed.
