One way that came to mind is use 2 for-loops

We can multiply/divide by 2 succesive using bitwise operators .
May be You are looking to The Vedas (Sanskrit वेद, véda, "knowledge") arithmetic .The product of the sum - Gunitasamuchyah.
(or Trachtenbergs system to speed multiply in memory).
quuba
byte a = 4;
byte b = (byte) (a >> 1);
byte c = (byte) (a >> 2);
byte d = (byte) (a << 1);
System.out.println(a);
System.out.println(b);
System.out.println(c);
System.out.println(d);(or Trachtenbergs system to speed multiply in memory).
quuba
I m still can't get the answer from u guys.....
Let me explain more in detail:
class add{
public static void main(String args[])
{
int a=2,b=2,c;
c=a+b;
System.out.println("C="+c);
}
}
This what we normally done using arith operator '+'.
I want the answer c=4 without using '+' or any arith operator.
Pls suggest ur ideas through the example.. i m a beginner in java so i can clearly understand... Hoping for u r answers......

c=a+b; - here is arithmetic operator .System.out.println("C="+c); - here is overloaded operator + . Here this mean CONCATENATION of two String-s.
You can asked: c is not a String type. Yes it is true, but c is casting to String automatically before join.
In Your case You can write:
System.out.print("C=");
System.out.println(""+c);// "" (an empty String) can cast integer to StringSystem.out.print("C=");
System.out.println(c);// "" automatic cast int to StringRemark: Sign + in arithmetic has two menings:
1. before a single number indicate, positive number
2. between two numbers , sum operation
Try write:
System.out.println(c++); orSystem.out.println(++c); try explain differencequuba
