counttest.java

Java 程序设计源码 只提供了部分

class Count {
	public int num;

	Count(int num) {
		this.num = num;
	}
}

public class CountTest {
	public static void main(String[] args) {
		Count count1 = new Count(0);

		int times = 0;

		for(int i = 0; i < 50; i++) 
			increment(count1,times);
			System.out.println("count1 is " + count1.num);
			System.out.println("times is " + times);
	}

	public static void increment(Count a,int times) {
		a.num++;
		times++;
	}
}
