Answer 1

Change the variable types as below. Array indices must be of type int.

public class BinSearch {
      public static void main(String [] args)
      {
          double set[] = {-3,10,5,24,45.3,10.5};
          int l = set.length;
          double temp;
          int i, j, first;
          System.out.print("Before it can be searched, this set of numbers must be sorted: ");
          for ( i = l-1; i>0; i--)
          {
              first=0;
              for(j=1; j<=i; j++)
          {
              if(set[j] < set[first])//location of error according to compiler
              {
                  first = j;
              }
              temp = set[first];
              set[first] = set[i];
              set[i] = temp;
          }
      }
  } 
}
