【自动化__持续集成】___java___数据类型转换

一、代码如下

package com.wujianbo;

public class Demo04 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		short si1= 100;
		int score=530001;
		System.out.println((short)score);
		
		int gdp1= 2147483647;
		long gdp2= 2147483648L;
		long l1= 345L;
		long l2= 1000;
		System.out.println(l1+l2);

	}

}

 二、代码如下

package com.wujianbo;

public class Demo05 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println(-1);
		System.out.println((int)-1);
		System.out.println((char)-1);
		System.out.println((byte)-1);

	}

}

三、代码如下

package com.wujianbo;

public class Demo05 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		long micro=24*24*60*1000*1000;
		long millis= 24*24*60*1000;
		System.out.println(micro/millis);

	}

}
