java参数传值

基本数据类型参数的传值

package Absent;public class chapter1 {public static void main(String[] args) {Computer com=new Computer();int b=100;int a=12;int result=com.add(b, a);System.out.println(result);result=com.add(b*12+2,a*12+3);System.out.println(result);}}class Computer{int add(int x,int y) {return x+y;}}

引用类型参数的传值 

package Absent;public class Chapter2 {public static void main(String[] args) {Abolish abolish=new Abolish(100);System.out.println("南孚电池的储量是："+abolish.electricityAmount);Absolute absolute=new Absolute();System.out.println("收音机开始使用南孚电池");absolute.openRadio(abolish);System.out.println("目前南孚电池的储存量为："+abolish.electricityAmount);}}class Abolish{int electricityAmount;Abolish(int amount){electricityAmount=amount;}//构造方法}class Absolute{void openRadio(Abolish abolish) {abolish.electricityAmount=abolish.electricityAmount-10;}//消耗的电量}
