Constants in Double class

static int MAX_EXPONENT

Maximum exponent a finite double variable may have.

static double MAX_VALUE

Largest positive finite value of type double.

static int MIN_EXPONENT

Minimum exponent a normalized double variable may have.

static double MIN_NORMAL

Smallest positive normal value of type double.

static double MIN_VALUE

Smallest positive nonzero value of type double.

static double NaN

Not-a-Number (NaN) value of type double.

static double NEGATIVE_INFINITY

Negative infinity of type double.

static double POSITIVE_INFINITY

Positive infinity of type double.

static int SIZE

The number of bits used to represent a double value.

The following code finds out the min/max value a double type variable can have. It also prints out the size of a double value.

public class Main {
  public static void main(String[] args) {
    System.out.println(Double.MAX_VALUE);
    System.out.println(Double.MIN_VALUE);
    System.out.println(Double.SIZE);

  }
}

The output:

1.7976931348623157E308
4.9E-324
64

public class Main {
  public static void main(String[] args) {
    System.out.println(Double.MAX_EXPONENT);
    System.out.println(Double.MIN_EXPONENT);
    System.out.println(Double.MIN_NORMAL);

  }
}

The output:

1023
-1022

public class Main {
  public static void main(String args[]) {

    double d = -10.0 / 0.0;
    if (d == Double.NEGATIVE_INFINITY) {
      System.out.println("d = " + d);
    }

  }
}

d = -Infinity
