泛型方法printPoint使用演示

package _5_29;

 

public class GeneMethodDemo {

public static void main(String[] args) {

NewPoint<Integer, Integer> p1 = new NewPoint<Integer, Integer>();

p1.setX(10);

p1.setY(20);

p1.printPoint(p1.getX(), p1.getY()); // Calling the generic method printPoint()

 

NewPoint<Double, String> p2 = new NewPoint<Double, String>();

p2.setX(25.4);

p2.setY("东经 180 度");

p2.printPoint(p2.getX(), p2.getY()); // Calling the generic method printPoint()

}

}

package _5_29;

 

 

class NewPoint<T1, T2> {

T1 x;

}

 

public T2 getY() {

}

 

// Define a method to print the point

public <S1, S2> void printPoint(S1 x, S2 y) {

System.out.println("This point is: " + m + ", " + n);

}
