Question

Java Program : Please save the program with the name ‘Dstring.java’

Write a program that reads a string from the keyboard. If the length of the string is an even number, your program should split the string into two strings of equal length. If the length of the string is odd, your program should split the string into two strings where the first part has one more character than the second part. Your program should output the two strings it created.

For example:

Input:          2BeOrNotToBe

Output:        2BeOrN

                       otToBe

Input:                  ToBeOrNotToBe

Output:           ToBeOrN

                       otToBe

Answer 1

Here is the code and yeah i made it public so you can save it as "Dstring.java".Hope,my answer helped you.Any firther doubts please feel free to ask us.

1. import java.util.*;
2. import java.lang.*;
3. import java.io.*;
4. import java.util.Scanner; //Needed for the Scanner class
5. /* Name of the class has to be "Main" only if the class is public. */
6. class Dstring
7. {
8. public static void main(String[] args)
9. {
10. //to hold the user's input
11. String intialstr;
12. String finalstr1=new String();
13. String finalstr2=new String();
14.   
15. //A Scanner object for keyboard input.
16. Scanner keyboard = new Scanner(System.in);
17.   
18. //Prompt the user to enter the string.
19. System.out.println("Please enter your string: ");
20. intialstr = keyboard.nextLine();
21. if((intialstr.length())%2==0){
22. for(int i=0;i<((intialstr.length())/2);i++){
23. finalstr1+=intialstr.charAt(i);
24. }
25. for(int i=(((intialstr.length()))/2);i<intialstr.length();i++){
26. finalstr2+=intialstr.charAt(i);
27. }
28. }
29. else{
30. for(int i=0;i<=((intialstr.length())/2);i++){
31. finalstr1+=intialstr.charAt(i);
32. }
33. for(int i=(((intialstr.length()))/2)+1;i<intialstr.length();i++){
34. finalstr2+=intialstr.charAt(i);
35. }
36. }
37. System.out.println("String 1="+finalstr1);
38. System.out.println("String 2="+finalstr2);
39.   
40. }
41. }

Output: (when even)

1. Please enter your string:
2. Amarkant
3. String 1=Amar
4. String 2=kant

Output:(when odd)

1. Please enter your string:
2. Amarkant2
3. String 1=Amark
4. String 2=ant2
