【java】泛型函数例子

【代码】

public class Test {
    private static <T> void print(T[] arr) {
        for(int i=0,n=arr.length;i<n;i++) {
            T t=arr[i];
            System.out.print(t+",");
        }
        System.out.println();
    }
    
    public static void main(String[] args) {
        String[] arr1= {"Andy","Bill","Cindy","Douglas"};
        print(arr1);
        
        Integer[] arr2= {1,2,3,6,7,8};
        print(arr2);
    }
}

【输出】
