如果没有关于您的问题的更多具体信息,很难回答您的问题,但这肯定有用:
It is difficult to answer your question without more specific information about your problem, but this would certainly work:
如果要在其他类中使用它,可以使用setter初始化其他类中的实例变量:
You can use a setter to initialize an instance variable in your other class if you want to use it everywhere in that class:
class someClass {
void someMethod() {
ABC ab = new ABC();
XYZ xyz = new XYZ();
xyz.setABC(ab);
}
}
class XYZ {
ABC ab;
//...
void setABC(ABC ab) {
this.ab = ab;
}
//...
void doSomething() {
// do something with instance variable ab
}
}
