Question

I’m working on creating a class file called “MyClass” – it works fine when I reference the class using the main class file and I can also make instances of the class with no problems by using this constructor method:

public MyClass(String x, int y) {
this.x = x;
this.y = y;
}

I run into the NoSuchElementException error when I put it in a loop and let it read data from a text document:

Scanner in = new Scanner(new FileReader(fileLocation));
//fileLocation is a var for the path

MyClass [] items = new MyClass[5];

for(int counter = 0; counter < 5; counter++) {
while(in.hasNextLine()) {
String x = read.next();
int y = read.nextInt();
items[counter] = new MyClass(x, y); //args require String, int
} 
}
in.close();

Here is the text file it is pulling from:

  string1    644
  string2    777

Thank you for any assistance.

Try this

Scanner in = new Scanner(new FileReader(fileLocation));
//fileLocation is a var for the path

MyClass [] items = new MyClass[5];

int counter = 0;
while(in.hasNextLine()) {
String x = read.next();
int y = read.nextInt();
items[counter++] = new MyClass(x, y); //args require String, int
if (counter >= 5) break;
} 

in.close();
