Comp Sci How to Capitalize the First Word After Reordering in Java?

[zzoo4]

Like this is my program to change the words around in order. Like First two words go to the back. What I am having trouble is, How do I capitalize the first at the results section after
the words order have changed??
This is my program.


import java.util. Scanner;

public class Starwars{
public static void main (String[]args){

//Declare Variables Section
int length, position=0;
String phrase, phrase2, phrase3;
Scanner input= new Scanner(System.in);

//Obtain Input From Section
System.out.println ("Enter your phrase: ");
phrase= input.nextLine();
length= phrase.length();
System.out.println (phrase);

//Perform Calculations Section
int i=0;
int i2=0;

while (i<length){

if (phrase.substring(i,i+1).equals(" ")){
i2++;
if (i2==2){
position=i;
}
}



i++;

}

phrase2=phrase.substring(position);

phrase3=phrase.substring(0,position);


System.out.println ("Yoda: " + phrase2 + ", " + phrase3);

}
}

When you post code, please put [noparse]

 and

[/noparse] tags around it. I have done that for your code.

A String object is immutable, which means that once you have initialized a string object, you can't change it.

I would recommend using the StringBuffer class, which has methods that let you insert characters into a string or set a character at a particular position. See http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/StringBuffer.html.
