不同整型数据类型在内存中占多大（字节），具体格式详见输出样例，输出样例中的?为不同整型数据类型在内存中占的字节数。输出样例如下：
The size of short is ? bytes.
The size of int is ? bytes.
The size of long is ? bytes.
The size of long long is ? bytes.
public class Main{ public static void main(String args[]){ System.out.println("The size of short is " + Short.SIZE / 8 + " bytes."); System.out.println("The size of int is " + Integer.SIZE / 8 + " bytes."); System.out.println("The size of long is " + Long.SIZE / 8 +" bytes."); System.out.println("The size of long long is " + Long.SIZE / 8 + " bytes."); }}
运行输出如下:
