Question about what this do.
Java Code:for(int i = 0; i<inputting; i++){ System.out.print("Enter Number "+(i+1) + ": "); num[i]= kbd.next(); System.out.print("Enter Original Base: "+(i+1) + ": "); x[i] = Integer.parseInt(kbd.next()); int l = num[i].length(); int v = 0; for(int j = l1; j>=0; j){ if(Character.isLetter(num[i].charAt(v))){ a = calculate(num[i].charAt(v)); } else a = Integer.parseInt(Character.toString(num[i].charAt(v))); z = z + (a*(int)Math.pow(x[i], j)); v++; // Returns the value of the first argument raised to the power of the second argument. }
especially the if else statement w/ math.pow.

You didn't write this piece of code yourself did you? No? Good, because it's a lousy way to convert a String representation of a number in any base to an integral number; w.r.t. that pow( ... ) method: the author commented the method in the last line of the 'elsepart' and because it's a method from the Math class it is completetly documented in the API documentation. My tip: throw that piece of code away and read the API documentation for the Integer class; it does exactly what you want and it does it without using that the pow( ... ) method.
kind regards,
Jos
