callbyvalue.java

JAVA编程思想源代码 值得一下 很难找的

package chapter6;

public class CallByValue {

	void meth(int i, int j) {
		i *= 2;
		j /= 2;
		System.out.println("i = " + i + " j = " + j);
	}

	public static void main(String[] args) {
		CallByValue ob = new CallByValue();
		int a = 15, b = 20;
		System.out.println("a and b before call: " + a + " " + b);
		ob.meth(a, b);
		System.out.println("a and b after call: " + a + " " + b);

	}
