Delete elements in a specified range in a linear list (such as an array or list) in Java

If you want to delete elements from a specified range in a linear list (such as an array or list) in Java, you can follow these steps:

  1. First, decide where to start and end where you want to delete. For example, suppose you have an array of integers and want to delete elements arrfrom index position startto .end

  2. Create a new linear table to store elements after deleting the specified interval.

  3. Use a loop to iterate over the elements in the original linear list.

    • If the index is not within the interval to be deleted (that is, the index is less than startor greater than end), the element is added to a new linear table.
    • If the index is within the interval to be deleted, the element is skipped and not added to the new linear table.
  4. Finally, assign the new linear table to the original linear table to complete the element deletion operation.

The following is a sample code to delete a specified interval of a linear table (array) in Java:

public static void deleteRange(int[] arr, int start, int end) {
    
    
    // 创建一个新的列表来存储删除区间后的元素
    List<Integer> newList = new ArrayList<>();

    // 遍历原始数组中的元素
    for (int i = 0; i < arr.length; i++) {
    
    
        // 如果索引不在要删除的区间内,则将元素添加到新的列表中
        if (i < start || i > end) {
    
    
            newList.add(arr[i]);
        }
    }

    // 将新的列表转换回数组,并将其赋值给原始数组
    arr = newList.toArray(new int[newList.size()]);

    // 打印删除区间后的数组,用于验证
    System.out.println(Arrays.toString(arr));
}

Please note that this is just a simple example code. In actual applications, you may need to perform appropriate boundary checking and error handling depending on the specific situation.
