Math class toDegrees() method

• toDegrees() method is available in java.lang package.
• toDegrees() method is used to convert an angle from radians to degrees.
• toDegrees() method is a static method, it is accessible with the class name too.
• toDegrees() method does not throw any exception.

Note: The result of conversion an angle from radians to degrees is not generally exact.

Syntax:

    public static double toDegrees(double angle_in_radians);

Parameter(s):

• angle_in_radians – represents the values of an angle in radians.

Return value:

The return type of this method is double – it returns the converted angle from radians to degrees.

Java program to demonstrate example of toDegrees() method

// Java program to demonstrate the example of 
// toDegrees(double angle_in_radians) method of Math Class

public class ToDegreesMethod {
    public static void main(String[] args) {
        // declaring the variables
        double d1 = 60;
        double d2 = -60;
        double d3 = 90;
        double d4 = -90;

        // displaying the values
        System.out.println("Angel values in radians...");
        System.out.println("d1: " + d1);
        System.out.println("d2: " + d2);
        System.out.println("d3: " + d3);
        System.out.println("d4: " + d4);

        // converting angel value from radians to degrees
        d1 = Math.toDegrees(d1);
        d2 = Math.toDegrees(d2);
        d3 = Math.toDegrees(d3);
        d4 = Math.toDegrees(d4);

        System.out.println("Angel values in degrees...");
        System.out.println("d1: " + d1);
        System.out.println("d2: " + d2);
        System.out.println("d3: " + d3);
        System.out.println("d4: " + d4);
    }
}
