Methods of Classes

Classes can have methods that operate on fields of the class

public class Coordinate {

public int x;

public int y;

// Set field x to p*p

public void setX(int p) {

x= p*p; }

// Set field y to q

public void setY(int q) {

y= q;}

// Return the sum of the squares of the fields

public int sumSquares() {

return x*x + y*y; }

}
