[英]Why doesn't my ImprovedBubbleSort method work?
This is my java code for array exercises at my school and I was wondering why even though everything here works when I try to use the ImprovisedBubbleSort method my program stops functioning这是我在学校进行数组练习的 Java 代码,我想知道为什么当我尝试使用 ImprovisedBubbleSort 方法时,即使这里一切正常,我的程序也会停止运行
public static void ImprovedBubbleSort(int [] array){
boolean swap;
int temp;
int max;
do {
swap=false;
max=1;
for (int i=0;i<array.length-max;i++){
if (array[i]>array[i+1]){
temp=array[i];
array[i]=array[i+1];
array[i+1]=temp;
swap=true;
}
max++;
}
}while (swap=true);
System.out.println("The numbers you entered in order are: ");
for (int j=0;j<10;j++){
System.out.println(array[j]);
}
}
}
It's important to realize that if you're using a single loop like in your example with that if statement you can find an instance of position 0 and 1 where it is sorted but the rest of the array may not be sorted.重要的是要意识到,如果您在示例中使用 if 语句中的单个循环,您可以找到位置 0 和 1 的实例,在该位置对其进行排序,但数组的其余部分可能未排序。 This will cause the if statement to not activate.这将导致 if 语句无法激活。
You can alleviate this problem by doing something like this:您可以通过执行以下操作来缓解此问题:
import java.util.Arrays;
public class MyClass {
public static void main(String args[]) {
int test[] = {7,1,9,1,5,6};
bubbleSort(test);
System.out.println(Arrays.toString(test));
}
static void bubbleSort(int[] arr) {
int n = arr.length;
int temp = 0;
for(int i=0; i < n; i++){
for(int j=1; j < (n-i); j++){
if(arr[j-1] > arr[j]){
//swap elements
temp = arr[j-1];
arr[j-1] = arr[j];
arr[j] = temp;
}
}
}
}
}
