然后再来看看值传递与引用传递两者的定义 值传递(pass by value)是指在调用函数时将实际参数复制一份传递到函数中,这样在函数中如果对参数进行修改,将不会影响到实际参数。 引用传递(pass by reference)是指在调用函数时将实际参数的地址直接传递到函数中,那么在函数中对参数所进行的修改,将影响
public static void main(String[] args){ int i = 100; int[] iArray = {1,2,3}; mod(i); System.out.println(i); mod(iArray); for(int k=0; k
Java is officially always pass-by-value. The question is, then, “what is passed by value?” As we have said in class, the actual “value” of any variable on the stack is the actual value for primitive types (int, float, double, etc) or the reference for reference types. That is,...

pass by reference 和pass by value 分别是指的是引用传递和值传递。1、对于原始数据类型，也就是int、 long、char之类的类型，是传值的，如果你在方法中修改了值，方法调用结束后，那个变量的值没用改变。2、对于对象类型，也就是object的子类，如果你在方法中修改了它的成员的值，那个修改是生效的...
The parameter passing mechanism in Java is pass-by-value example: publicclassTest{publicstaticvoidmain(String[] args){ testa a =newtesta(); a.a=1; testa b =newtesta(); b.a =13; a.next = b; fool(a); System.out.println(a.a); ...
