I have 2 class in 2 package: class ClassOne in package1 and clas ClassTwo in package2. Class ClassTwo extends class ClassOne which have a protected constructor: protected ClassOne(String s). When i call protected constructor of ClassOne in constructor of ClassTwo it get none error but i can see it when do ctrl+space, it just show a public constructor super(). So what is this problem, why IDEs not show protected constructor when i ctrl+space?
package package1;
public class ClassOne {
public ClassOne(){
}
protected ClassOne(String s){
System.out.println(s);
}
}
package package2;
import package1.ClassOne;
public class ClassTwo extends ClassOne{
public ClassTwo(){
super("Why this protected constructor can use but not visiable?");//i can use this constructor protected ClassOne(String s) but can see it when ctrl+space
}
}
