你的代码是这样的吗？eclipse快捷键 Ctrl+Shift+F，格式化代码
public class ParentClass {
public int overrideValue;
public ParentClass() {
overrideValue = 3;
}
public void showOverrideValue() {
System.out.println("overrideValue的值是:" + overrideValue);
}
}
public class SubClass extends ParentClass {
public class Test2 {
}
public static void main(String[] args) {
SubClass sub = new SubClass();
ParentClass parent = new ParentClass();
System.out.println(parent.overrideValue);
System.out.println(sub.overrideValue);
parent.showOverrideValue();
sub.showOverrideValue();
}
} |
