WRITE A PROGRAM IN JAVA TO IMPLEMENT BUBBLE SORT?

class bubble_sort
{
  public static void main(String args[])
{int a[]={2,5,4,6,7};
 int i, j,t=0;
int n=a.length;
    for(i = 0; i < n; i++)
{
      for(j = 1; j < (n-i); j++)
{
        if(a[j-1] > a[j])
{
          t = a[j-1];
          a[j-1]=a[j];
          a[j]=t;
        }
      }
    }
System.out.print("Sorted Array:");
for(i=0;i<a.length;i++)
System.out.print("\t" +a[i]);
  }
}
