For the String (int), can not find the appropriate constructor
String [] name=new String (renshu);

Two mistakes

CodePudding user response:

Do homework do stupid someone answer? thank you

CodePudding user response:

String [] name=new String (renshu);//this array on the left, the right is a String object, can type different assignment?
Change
String [] name=new String [renshu];//on the right side of the new array object also

Similarly
String [] courcs=new String (courcsNum);
Also to
String [] courcs=new String [courcsNum];
