Question

Java Eclipse program

Write statements to declare and initialize eight constants, one for each of the
primitive types in Java. boolean, byte, char, short, int, long, float and double. Add statements to print the name of the constant and its value to
your VariableDefinitions.javaprogram and compile the program. Assign a new
value to one of the constants and compile.
Comment out the lines of code that cause compilation errors but do not delete them
and recompile your program.

CODE

public class VariableDefinitions {
    public static void main(String[] args) {
        final boolean flag = true;
        final byte b = 1;
        final char c = 'A';
        final short s = 23;
        final int i = 134;
        final long l = 1234566;
        final float f = 123.45f;
        final double d = 1245.67899;

        System.out.println("flag = " + flag);
        System.out.println("b = " + b);
        System.out.println("c = " + c);
        System.out.println("s = " + s);
        System.out.println("i = " + i);
        System.out.println("l = " + l);
        System.out.println("f = " + f);
        System.out.println("d = " + d);

        // flag = false; // this line causes compilation error
    }
}
