thisis a reference to the current object, and is implicitly passed into non static methods.
this.xdereferences the reference to get to the "x" attribute.
this是对当前对象的引用，并隐式传递给非静态方法。
this.x取消引用以获取“x”属性。
Use it if you want to disambiguate between a function argument and a class member.
如果您想消除函数参数和类成员之间的歧义，请使用它。
public void setX(int x)
{
this.x= x;
}
It is valid but redundant in this scenario:
在这种情况下它是有效但多余的：
public void setX(int xValue)
{
this.x= xValue;
}
Or simply:
或者干脆：
public void setX(int xValue)
{
x= xValue;
}
