冒泡排序法，为什么没有结果出来呢？求大侠，帮忙看看

[jianyuzhimei]

public class BubbleSort {
public static void main(String args[]){
double[] a={5.0,4.4,1.9,2.9,3.4,3.5};
boolean changed=true;
do{
changed=false;
for(int j=0;j<=a.length-2;j++)
if(a[j]>a[j+1]){
swap(a,j);
changed=true;
}
}
while(changed);
}
public static void swap(double[] array,int i){
double temp=array[i];
array[i]=array[i+1];
array[i+1]=temp;
}
}

根本没有输出语句啊，
public class BubbleSort {
public static void main(String args[]){
double[] a={5.0,4.4,1.9,2.9,3.4,3.5};
boolean changed=true;
do{
changed=false;
for(int j=0;j<=a.length-2;j++)
if(a[j]>a[j+1]){
swap(a,j);
changed=true;
}
}
while(changed);
for(int i=0;i<a.length();i++)
System.out.println(a[i]);
}
public static void swap(double[] array,int i){
double temp=array[i];
array[i]=array[i+1];
array[i+1]=temp;
}
}

[看着星星写代码]

public class BubbleSort {/*冒泡排序*/
public static void main(String args[]){
double[] a={5.0,4.4,1.9,2.9,3.4,3.5};
boolean changed=true;
do{
changed=false;
for(int j=0;j<=a.length-2;j++)
if(a[j]>a[j+1]){
swap(a,j);
changed=true;
}
/*for(int j=0;j<=a.length-2;j++)
{
System.out.println(a[j]);
}*/
}
while(changed);
for(int j=0;j<=a.length-1;j++)
{
System.out.println(a[j]);
}
}
public static void swap(double[] array,int i){
double temp=array[i];
array[i]=array[i+1];
array[i+1]=temp;

}

}

没输出呢

谢谢大侠们！

想看结果好歹加一句输入吧

public class BubbleSort {
	public static void main(String args[]) {
		double[] a = { 5.0, 4.4, 1.9, 2.9, 3.4, 3.5 };
		boolean changed = true;
		do {
			changed = false;
			for (int j = 0; j <= a.length - 2; j++)
				if (a[j] > a[j + 1]) {
					swap(a, j);
					changed = true;
				}
		} while (changed);
		for (double d : a) {
			System.out.println(d);
		}
	}

	public static void swap(double[] array, int i) {
		double temp = array[i];
		array[i] = array[i + 1];
		array[i + 1] = temp;
	}
}
