方法的值传递机制练习
package six;
public class TestValue {
}
class Value {
int i = 15;
}
class Test {
public static void main(String argv[]) {
Test t = new Test();
t.first();
}
public void first() {
int i = 5;
Value v = new Value();
v.i = 25;
second(v, i);
System.out.println(v.i);
}
public void second(Value v, int i) {
i = 0;
v.i = 20;
Value val = new Value();
v = val;
System.out.println(v.i + " " + i);
}
}
