ok.. i have to write this program that does and shows all the steps for long multiplication.. this is what i have for my program.. i just need someone to tell me if i'm completely wrong or ok...
/*
longMulti.java
Task: program to output the product of two integers in "long" multiplication format.
*/
import java.io.*;
public class longMulti {
public static void main (String[] args) throws Exception {
public long longValue () {
return left.num() * right.num();
BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in),1);
int num1;
int num2;
int sum1=0;
int sum2=0;
System.out.println("Enter a two-digit number.");
num1 = Integer.parseInt(keyboard.readLine());
System.out.println("Enter another two-digit number.");
num2 = Integer.parseInt(keyboard.readLine());
if (-100<num1<100 && -100<num2<100) do {
System.out.println(" " + num1);
System.out.println("x" + num2);
System.out.println("__________");
sum1=(right.num2 * right.num1) + (right.num2 * left.num1 * 10)
System.out.println(sum1);
sum2=(left.num2 * 10 * right.num1) + (left.num2 * 10 * left.num1 * 10)
System.out.println(sum2);
System.out.println("__________")
System.out.println(sum1 + sum2);
else System.out.println("Invalid Input");
}
}
}
}
thanks
