成员变量和本地方法变量可以具有相同的名称吗？ [英] Can member variable and local method variable have the same name?

问题描述

我如何做到这一点？

class Test {
    private int var1;

    public Test(int var1) {
        var1 = var1; //set the member variable to what was passed in
    }
}

我确信有一个非常明显的答案。它现在正在逃避我。

I'm sure there's a very obvious answer. It's just escaping me right now.

推荐答案

是的，他们可以共享相同的名称。但是，要引用实例变量，您需要使用此前缀：

Yes, they can share the same name. However, to reference the instance variable, you need to use the this prefix:

public Test(int var1) {
    this.var1 = var1;
}
