Input ila undi

1 + 1 + 1

2 + 2

3 + 1 - 2

2 + 3 + 2

1 + 3 + 2 + 9

 

Output ila ravali 

1 + 1 + 1 = 3

2 + 2 = 4

3 + 1 - 2 = 2

2 + 3 + 2 = 7

1 + 3 + 2 + 9 = 15

 

Ela ?? Regular expression vadala ??

Please note you need to have jdk1.6

good one ...
to generalize we can make main logic into a method and pass every input as a parameter :)

import java.io.IOException;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

public class CSVParsing {

	 public static void main(String args[]) throws IOException
	 { 
		 
		 calculate("5+3");
	 }

	private static void calculate(String string) {
		 ScriptEngineManager mgr = new ScriptEngineManager();
		 ScriptEngine engine = mgr.getEngineByName("JavaScript");
		// String foo = "40+2";
		 try {
			System.out.println(engine.eval(string));
		} catch (ScriptException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}		
	}
}

Thanks a lot :)

This seems to be a simpler way...kani recursive loops like using for loop or while tho try chestunna ... trying to read the input and calculating the sun based on arithmetic operation.

 

Because if u use ScriptEngine  that will just calculate and throwing the out but I need to have output in this format

Input = Output 

 

1 + 1 + 1 = 3

2 + 2 = 4

3 + 1 - 2 = 2

2 + 3 + 2 = 7

1 + 3 + 2 + 9 = 15

 

ila undali ... so alantappudu .. I have to use the recursive loops kada .. is there any other way

learning lo vunnava ? If this ur assignment .. nuvvu adiginadhi simple task eh .. already pyna vunna code ni small modifications chesthe output ni nuvvu anukunna format lo present cheyochu .. try cheyyi ..

 

hint :  no need to use loops unless u need to give all the input parameters/exressions at a time ..

 

try chesi rapothe cheppu .. :)

Not learning working A ... but it's kind of assignment ... Thanks I will try

akkada logic ee line lo undi ? ee java thoti idey problem...
