java - 在Core java中按升序对数组元素进行排序？

Question

class Ascendingarray { 
    public static void main(String[] args) {  //Without using Arrays.sort function 
        int i; int nos[] = {12,9,-4,-1,3,10,34,12,11};       
        System.out.print("Values before sorting: \n"); 

        for(i = 0; i < nos.length; i++) 
            System.out.println( nos[i]+" "); 
        //sort(nos, nos.length); 
        System.out.print("Values after sorting: \n"); 
        for(i = 0; i

Answer 1

您可以使用冒泡排序等排序方法自行排序。使用嵌套的 for 循环。

    for (int j = 0; j<array.length; j++) {
        for (int k = 0; k < array.length; k++){
            if (array[j] < array[k]) {
                int buffer = array[j];
                array[j] = array[k];
                array[k] = buffer; 
            }
        }
    }
