i have made a program in java *** groovy to balance an array by modifying the values (except the largest one) according to a given input which is a number . i have written the following code but i also have to include the functionality in which the difference between the smallest and largest element should also gets minimized ..so plz help guys??

def input;
def diff , rem;
def extra ,each
def t,k;
def t1;
int  j;
result_final = new SimpleResults();
def a =[0,0,0,0]
def ind =[0,0,0,0]
int i=0;
while(res_set.next())                  // for converting result set into array list
{ if(i>=0 && i<4)
{   ind[i] = res_set.getValue("col1");
    a[i] = res_set.getValue("col2");
    ++i;
    }
    else 
    {
    input= res_set.getValue("col2");
    }
} 

  for(i=0; i<4; i++)                  
  {
   for(j=1; j<(4-i); j++)
   {
    if(a[j-1]>a[j])
    {
       t = a[j-1];
       t1 = ind[j-1];
       a[j-1]=a[j];
       ind[j-1]=ind[j];
       a[j]=t;
       ind[j]=t1;
       }
  }
  }
  i=0;
 
diff =a[3]-a[0];                      
if (diff <= input)
{
     a[0]=a[0]+ diff;
    rem = input-diff;
    for(j = 0;j < 4;j++)
    {
        if((j!= 0)&&(j!= 3)&&(rem > 0))
        {
            diff = a[3]-a[j];
            if(diff <= rem)
            {
                 a[j]+=diff;
                 rem = rem-diff;
            }
            else
            {   a[j]+=rem;
                 rem=0;
            }
        }
    }
}
else
{
    a[0]+=input;
}


if (rem > 0)                                 // for  allocating remaining value
{
    if (rem == 1)
    {
        a[0] += 1;
    }
    else if (rem == 2)
    {
        a[0] += 1;
        a[1] += 1;
    }
    else if (rem == 3)
    {
        a[0] += 1;
        a[1] += 1;
        a[2] += 1;
    }
    else if (rem >= 4)
    {
        extra = rem%4 ;
        rem=rem-extra;
        each =rem/4;
         for(k = 0;k<4;k++)
        {
            a[k] +=each;
        }
        if (extra > 0)                                 // for  allocating remaining value
{
    if (extra == 1)
    {
        a[0] += 1;
    }
    else if (extra == 2)
    {
        a[0] += 1;
        a[1] += 1;
    }
    else if (extra == 3)
    {
        a[0] += 1;
        a[1] += 1;
        a[2] += 1;
    } 
    }
}
}

//its working properly but not following the second criteria

Moved to the correct forum, and code tags added.

This code cannot be compiled, as is, as Java. You have to have a main method, a class, etc.

You also haven't given us the details of what it's supposed to do. It accepts input, does something to minimize something based on... huh?
