Question

Write a Java method that takes a String as its input and prints on the first line the odd characters (1^st, 3^rd, etc) and on the second line the even characters (2^nd, 4^th, etc).

Answer 1

import java.util.*;

class EvenOddChars
{
public static void main (String[] args)
{
  Scanner input = new Scanner(System.in);
  
  //input the string
  System.out.println("Enter the string : ");
  String str = input.next();
  
  evenOddChars(str);
  
  
}

public static void evenOddChars(String str)
{
  //display odd characters
  System.out.println("\nOdd Characters : ");
  for(int i=1;i<str.length();i+=2)
  System.out.print(str.charAt(i)+" ");
  
  System.out.println();
  
  System.out.println("\nEven Characters : ");
  //display even characters
  for(int i=0;i<str.length();i+=2)
  System.out.print(str.charAt(i)+" ");
}
}

output:

Enter the string :abcdefghijklmnop

Odd Characters :
