Intermediate Java(19) - Generic Return Types

import java.util.*;

public class apples{

public static void main(String[] args){

System.out.println(max(23,42,1));

System.out.println(max("apples","tots","chicken"));

}

public static <T extends Comparable<T>> T max(T a,T b, T c){

T m = a;

if(b.compareTo(a) > 0)

m = b;

if(c.compareTo(m)> 0)

m=c;

return m;

}

}

<T extends Comparable<T>> T max(T a,T b, T c){ → Comparable用於比較, max是函數名稱

這是運行時的結果:  

42
