        for (int i = 0; i < n; i++) 
        {
            a[i] = sc.nextInt();
        }
        for (int i = 0; i < n; i++) 
        {
            for (int j = i + 1; j < n; j++) 
            {
                if (a[i] < a[j]) 
                {
                    temp = a[i];
                    a[i] = a[j];
                    a[j] = temp;
                }
            }
        for (int i = 0; i < a.length; i++) 
        {
          a[i]=sc.nextInt();
       }
            System.out.print(a[i] + " ");
        }
     }
}

What I have tried:

error:cannot find symbol
System.out.print(a[i]+" ");
^
Symbol:variable i
Location:class main
I am getting like this.

If you fixed your indentation it would be obvious that you have closed your for loop too early:

Java

 for (int i = 0; i < a.length; i++)
 {
   a[i]=sc.nextInt();
}          // <----- this ends the scope of variable i remove this brace
     System.out.print(a[i] + " ");  // the variable i does not exist here.
 }

You haven't declared temp at all, you have two different declarations of i in the same scope:

Java

        for (int i = 0; i < n; i++) 
            {
            for (int j = i + 1; j < n; j++) 
                {
...
                }
            for (int i = 0; i < a.length; i++) 
                {
...
                }
...
            }

You bubble sort some values, then overwrite them all again ...

That looks like it was thrown together without any significant thinking about what you expected to produce.
Stop and think about what you are doing before you start coding: it will save you a lot of time in the long run! This may help you: How to Write Code to Solve a Problem, A Beginner's Guide[^]
