How to cast float to byte value in Java

ConvertFloatToByteExample1.java 

public class ConvertFloatToByteExample1 {
    public static void main(String[] args) {
        float value1 = 56.78F;
        byte value2 = (byte) value1;

        System.out.println("float value: " + value1);
        System.out.println("byte value: " + value2);
    }
}
The output is: 
float value: 56.78
byte value: 56

Using Float.byteValue() method to get byte value from a Float object

ConvertFloatToByteExample2.java 

public class ConvertFloatToByteExample2 {
    public static void main(String[] args) {
        Float value1 = 23.45F;
        byte value2 = value1.byteValue();

        System.out.println("float value: " + value1);
        System.out.println("byte value: " + value2);
    }
}
The output is: 
float value: 23.45
byte value: 23
