Example:

public class ClassName{

   private int attribute1;                        //attribute

   private String attribute2;                     //attribute


   public ClassName(){                            //constructor

       attribute1 = 2;

       attribute2 = "word";

   }


   public void printAll(){                        //method

      System.out.println(attribute1 + " " + attribute2);

   }


   public int getAttribute1(){                    //method

      return attribute1;

   } 


   public void setAttribute2(String attribute2){  //method

      this.attribute2 = attribute2;

   }

}

The syntax to do it is above, but if you are struggling on what exactly they should do/hold then it's best to think as real-world as possible (unless you are given exact attributes to create). So you should create attributes to hold things age, student number, name etc etc.

It is then best to have these as private attributes (so outside classes cannot tamper with them in a way which is out of your control), so you should create set and get methods as above. Get which returns the attribute, and set which changes an attribute to one given as a parameter. :)

You then add any methods that you need to, to carry out anything else you might need from a student object.
