Program:

 public class WrapperacosMethod {

    public static void main(String args[]) {
	      double degrees = 60.0;
	      double radians = Math.toRadians(degrees);

	      System.out.format("The value of pi is %.4f%n", Math.PI);
	      System.out.format("The arccosine of %.4f is %.4f degrees %n", Math.cos(radians),
	         Math.toDegrees(Math.acos(Math.sin(radians))));
	   }
}

/* 
Returns the arccosine of the specified double value. 
*/

Output:

The value of pi is 3.1416
The arccosine of 0.5000 is 30.0000 degrees
