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
	
}
