For number 1, look up java.util.Scann er, for number 2 look up printf in java

see i will give you a logic for 2nd q.
ex:consider the no.34.12345=x
step1:you need to extract each integer value from the no.ie 3 4 . 1 2 3 4 5
step2:you need to concatinate "0.0" to the values preceding from 2nd decimal
ie 0.02345=y
step3:you subtract z=x-y
z=34.12345-0.02345=34.1


***if confused reply. i will send the codes

If you have a problem, you'd better start your own thread and explain your problem there clearly.

class Scanner is for inputting information. For output use the class Formatter which enables C type printf() formatting, e.g.

import java.util.*;
import java.io.*;

public class Test
{
   public static void main (String [] args)
    { 
     double num1=34.4444444;
     System.out.println("num1 = " + num1);
      StringBuilder stringBuilder = new StringBuilder();
      Formatter outputStr = new Formatter(stringBuilder);
      outputStr.format("using formatter num1 = %4.2f ", num1);
      System.out.println(outputStr);
     }
}

when run gives
num1 = 34.4444444
using formatter num1 = 34.44

We were hoping he/she'd be able to do this for themselves. However, you seem to have missed requirement 1 for the original post.
