Yes.
That is what I consider the missing default parameter issue.
In some languages:
public Demo(String name, int answer, boolean prisoner)
{
this.name = name;
this.number = number;
this.isPrisoner = prisoner;
}
public Demo(String name)
{
super(name, 6, true);
}
can be made as:
// **** NOT JAVA ****
public Demo(String name, int answer = 6, boolean prisoner = false)
{
this.name = name;
this.number = number;
this.isPrisoner = prisoner;
}
