Problem:
What are sizes of Java primitive types?
Solution:
The following program answers the question:
package com.farenda.solved;
public class JavaSolved {
public static void main(String[] args) {
System.out.println("Sizes of Java primitive types:");
int charMin = Character.MIN_VALUE;
int charMax = Character.MAX_VALUE;
System.out.println("Character min: " + charMin + ", max: " + charMax);
System.out.println(" Byte min: " + Byte.MIN_VALUE + ", max: " + Byte.MAX_VALUE);
System.out.println(" Short min: " + Short.MIN_VALUE + ", max: " + Short.MAX_VALUE);
System.out.println(" Integer min: " + Integer.MIN_VALUE + ", max: " + Integer.MAX_VALUE);
System.out.println(" Long min: " + Long.MIN_VALUE + ", max: " + Long.MAX_VALUE);
System.out.println(" Float min: " + Float.MIN_VALUE + ", max: " + Float.MAX_VALUE);
System.out.println(" Double min: " + Double.MIN_VALUE + ", max: " + Double.MAX_VALUE);
}
}
Result:
Sizes of Java primitive types:
Character min: 0, max: 65535
Byte min: -128, max: 127
Short min: -32768, max: 32767
Integer min: -2147483648, max: 2147483647
Long min: -9223372036854775808, max: 9223372036854775807
Float min: 1.4E-45, max: 3.4028235E38
Double min: 4.9E-324, max: 1.7976931348623157E308
As you can see all numeric types are with sign!
