public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("intMin:" + Integer.MIN_VALUE + ";intMax:" + Integer.MAX_VALUE);
        System.out.println("shortMin:" + Short.MIN_VALUE + ";shortMax:" + Short.MAX_VALUE);
        System.out.println("longMin:" + Long.MIN_VALUE + ";longMax:" + Long.MAX_VALUE);
        System.out.println("byteMin:" + Byte.MIN_VALUE + ";byteMax:" + Byte.MAX_VALUE);

        System.out.println("floatMin:" + Float.MIN_VALUE + ";floatMax:" + Float.MAX_VALUE);
        System.out.println("doubleMin:" + Double.MIN_VALUE + ";doubleMax:" + Double.MAX_VALUE);
    }
}

int是基本数据类型，Integer是对int进行了封装的一个类。
