[FIXED] pass data by user to another class

Issue

I try pass student names from main class to students class but I get error through runtime.

Main class is

 public static void main(String[] args) {
              Students students =new Students ();
              Scanner in = new Scanner (System.in);
              String [] name = new String [5];
              for (int i =0; i <=4; i++){
              System.out.print("Enter student name " + (i+1) + " : ");
                       name [i]= in.next();  
              }
              students.SetData(name);
              students.GetData();

     }// Main

Students class is

public class Students {
    private String Names [] = new String [5]; 
    
    public void SetData (String [] Names){
              for (int i=0 ; i <= Names.length; i++){
                       this.Names [i] = Names[i] ; //HERE is my error
              } //for 
    } //SetData method
    
    public void  GetData (){
              for (int i=0 ; i <= Names.length; i++){
                       System.out.println("Name of student " + (i+1) + " is " +Names[i]);
              } //for
    } //GetData mehtod 
} //Students Class

Also how can I make my program check if user entered STRING or not ?

THANKS ALL

Solution

You should write i < Names.length in your loops, so they terminate one step earlier.

Names.length == 5, i.e. one greater than the last valid index.

Nitpicks: You shouldn't start variables with capital letters, they're reserved for class names. Using space before the [] array operator also looks weird.
