Defines an array that gets the maximum and minimum values in the array

Ideas:

We define an array and then define a max variable to store the maximum value;

Then define a min variable to store the minimum value;

We iterate through the array, and if the current value is greater than Max, the current value is assigned to Max;

If the current value is less than min, the current value assigned to min;

Let's give the sample code:

1 2 3 4 5 6 7 8 9 A-public  class  test {       public  static  void  Main (String[] args)  {          int  arr[]= new  int []{1, 6, 7,-2}; //  set Semantic an array          int  max=arr[0]; //  The 1th element in the data save Max           int  min=arr[0]; //  The 1th element in the data save min           for (int  i= 1; i<arr.length;i++) { //  traverses the array starting with the second element               if (arr[i]>max) {
