Getting the last integer in a for loop and checking if the new one is equal to that

[ocomobock]

Basically, I'm trying to make a program that makes fake and randomized conversations on forums. This is the output:

What do you call outer space? Outer space.

10/10 would read again

lolololol rofl hahaha xD

XD im literaly crying right now

As you can see, it sometimes makes the same user quote themselves, which I don't want.

package b;

import java.util.Random;

public class Test2 {
	
	static Random r = new Random();
	static int rNum1 = r.nextInt(10000);
	static int rNum2 = r.nextInt(10000);
	static int rNum3 = r.nextInt(10000);
	static int max = 16;
	static int maxd2 = max / 2;
	static int g1;
	static int g2;
	static int g3;
	static int g4;
	static String names[] = {"ILikeJokes", "GimmeSomeJokes", "jokesRgreat17"};
	static String messages[] = {"lolololol rofl hahaha xD", "XD im literaly crying right now", "10/10 would read again"};
	static String sourceMsg[] = {"Hey guys, I just thought of a really funny joke! What do you call a mouse without a keyboard? A perfectly normal mouse.", "What do you call outer space? Outer space."};
	static String sourceName[] = {"FunnyDude" + rNum1, "LaughingIsGreat" + rNum2, "xXMyJokesRock" + rNum3 + "Xx"};
	
	public static void main(String args[])
	{
		if (messages.length == names.length)
		{
			for(int i = 0; i < max; i++)
			{
				g1 = r.nextInt(names.length);
				g2 = r.nextInt(messages.length);
				g3 = r.nextInt(sourceMsg.length);
				g4 = r.nextInt(sourceName.length);
				if(i < maxd2)
				{
					if (i == (maxd2 - 2))
					{
						System.out.print("[quote=\"" + sourceName[g4] + "\"]");
					}else
					{
						System.out.print("[quote=\"" + names[g1] + "\"]");
					}
				}else
				{
					if (i == (maxd2))
					{
						System.out.print("[/quote]" + sourceMsg[g3]);
					}else
					{
						System.out.print("[/quote]" + messages[g2]);
					}
				}
			}
		}else
		{
			System.err.print("The amount of names must be equal to the amount of messages!");
		}
	}
}

I know it has something to do with do while loops, but I get confused by those. I haven't done anything with Java for a while so I can't really remember how do while loops work. Any help would be appreciated.

I don't think that is something we'd be interested in having on this forum.

Haha yeah, forgot to mention this is for another forum. I'm just doing this cause I'm bored and the other forum is really inactive.
