Day012 application of one-dimensional array

           There is a group of students' achievements {99,85,82,63, 60}, Arrange them in descending order .
           To increase the performance of a student , Insert it into the grade sequence , And keep descending .
          
           Ideas :
          1) Create a new array that is longer than the original array 1 Array of
          2) Store the elements in the original array into the new array in order
          3) Use Scanner Gain and increase students' achievements
          4) Get the position of the inserted element to be inserted through circular comparison
          5) The elements starting from the insertion position and then
         
        int[] scores = { 99, 85, 82, 63, 60 };

        // 1) Create a new array that is longer than the original array 1 Array of
        int[] newScores = new int[scores.length + 1];

        // 2) Store the elements in the original array into the new array in order
        for (int i = 0; i < scores.length; i++) {
            newScores[i] = scores[i];
        }
        
         // 3) Use Scanner Gain and increase students' achievements
        Scanner sc = new Scanner(System.in);
        System.out.println(" Please enter the student grade you want to increase :");
        int insert = sc.nextInt();
        
        // 4) Get the position of the inserted element to be inserted through circular comparison
        int index=newScores.length-1;
        for (int i = 0; i < newScores.length; i++) {
            if(insert>newScores[i]){
                index=i;
                // Once the obtained element meets the conditions , No more comparisons
                break;
            }
        }
        
        // 5) Move back one bit from the insertion position and the following elements ( Be careful : When moving , Move back and forth ; Subscript from 0 At the beginning )
        for(int i = newScores.length-1;i>index;i--){
            newScores[i]=newScores[i-1];
            
        }
        
        // 6) Put the inserted element in the corresponding position
        newScores[index]=insert;
        
        // Traverse
        for(int i=0;i<newScores.length;i++){
            System.out.print(newScores[i]+" ");
        }
