How to implement the minimum value in an array in java

Purpose:

First create an array with a length of 5, then assign a random integer to each bit of the array, and find the smallest (largest) value come out.

Method 1:

        int array[] = new int[5];
        System.out.println("数组的元素为：");
        for (int i=0;i<array.length;i++){
            array[i] = (int) (Math.random()*100);
            System.out.println(array[i]);
        }
        System.out.println("----------------------------------------------------");
        int min = array[0];
        for(int i=1;i<array.length;i++)
        {
            if(min>array[i]){
                min=array[i];
            }

        }
        System.out.println("方法二：最小值为："+min);
    }

Result:

Method 2:

        int array[] = new int[5];
        System.out.println("数组的元素为：");
        for (int i=0;i<array.length;i++){
            array[i] = (int) (Math.random()*100);
            System.out.println(array[i]);
        }
        System.out.println("----------------------------------------------------");
        //对数组进行排序处理
        Arrays.sort(array);
        System.out.println("方法三：最小值为："+array[0]);
    }

Result:

##Method 3:

Collections through Collections class .max() and Collections.min() methods to find the maximum and minimum values ​​in an array.

The code is as follows:

        Integer array[] = new Integer[5];
        System.out.println("数组的元素为：");
        for (int i=0;i<array.length;i++){
            array[i] = (int) (Math.random()*100);
            System.out.println(array[i]);
        }
        System.out.println("----------------------------------------------------");
        //通过 Collections 类的 Collections.max() 和 Collections.min() 方法来查找数组中的最大和最小值：
        int min = (int)Collections.min(Arrays.asList(array));
        int max = (int) Collections.max(Arrays.asList(array));
        System.out.println("方法四：最小值为："+min);
        System.out.println("方法四：最大值为："+max);

Result:
