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.
Java中没有long long

public class Main{ public static void main(String[] args) { System.out.println("The size of short is "+Short.BYTES+" bytes."); System.out.println("The size of int is "+Integer.BYTES+" bytes."); System.out.println("The size of long is "+Long.BYTES+" bytes."); System.out.println("The size of long long is "+ Long.BYTES+" bytes."); } }
java哪有longlong。。
个人觉得java答案:
public static void main(String[] args){ System.out.println("The size of byte is "+Byte.SIZE+" bytes."); System.out.println("The size of short is "+Short.SIZE+" bytes."); System.out.println("The size of int is "+Integer.SIZE+" bytes."); System.out.println("The size of long is "+Long.SIZE+" bytes."); }
要通过的答案:
public class Main{ public static void main(String[] args){ System.out.println("The size of short is 2 bytes."); System.out.println("The size of int is 4 bytes."); System.out.println("The size of long is 8 bytes."); System.out.println("The size of long long is 8 bytes."); } }
