Classes can have methods that operate on the 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;

}

}
