System.out.println("the original array is :
"+Arrays.toString(aee));
bubble(aee);
}
public static void swap(int a, int b){
int c =a;
a=b;
b=c;
}
public static void bubble(int ary[]){
int l = ary.length;
int lo =0 , hi =l-1;

for(int i=0; i<hi; i++)
{
for(int j=0; j<hi-1; j++)
{
if(ary[i]>ary[j+1])
swap(ary[j],ary[j+1]);
}
}
print(ary);
}
public static void print(int arr[]){
int l = arr.length;
System.out.println("the array is : ");
for(int i=0; i<l-1; i++)
{

Answer 2

Array are pass by refference but not it individual values, so swap function will not work that way...

Corrected code:

public static void bubble(int ary[]){
int hi= ary.length;

for(int i=0; i<hi; i++)
{
for(int j=0; j<hi-1; j++)
{
if(ary[j]>ary[j+1])
{
int c =ary[j];
ary[j]=ary[j+1];
ary[j+1]=c;
}
}
}

System.out.println("the array is : ");
for(int i=0; i<hi; i++)
System.out.print(ary[i]+",");
}
