yay last min uni work part 2.... I need help

[Rossmac]

If(replay.!equals("Y") && replay.!equals("N"))

I think you also do need the .equals part and the == doesn't work with Strings.

Im currently trying to scan grid 2 for any number over 0, and each time it finds a number over 0 to add one to the "Uncovered" score but Im not doing very well

This:

for(int x=0;x<7;x++){
for(int y=0;y<8;y++){

if(grid2[x][y]>0);
uncovered++;

}
}

Not that I've actually written any Java code in the last 5 years, but I think you might want to check the correct syntax for an "if" statement.

You're making the array too complicated. There's no need to make one 56 length array. Can you imagine the work in parsing that to generate the output?

In C: int i, b[56]; for(i=0;i<56;i++)printf("%c%s"," " *£"[b<3 ? b : 0],i%8==0?"\n":"");

(Not a terribly serious suggestion, but 1D arrays are often actually a good choice for these things if efficiency matters and you know what you're doing).

 

[Rossmac]

Yeah I explained his syntax for If statements a while ago, I think he has got it sorted now...

 

[Welshy]

Please can I hire one of you as my java buddy

Who'd say no to an offer like that

 

[Rossmac]

Who'd say no to an offer like that

my thoughts exactly!

 

[Chrisss]

Are you using the

tags? Use the

 tags and it'll keep your indentation so code is easier to read.

 

[benjo plz.]

That's what I did :\.

 

[Rossmac]

I *think* you can still compare strings using ==, just not =.

I'm just saying I don't think you can compare using ==, and you do need the equals method, like you showed.

 

[Una]

== Compares the references (I.e if they both refer to the same string object on the heap). .equals() is what you wish to use to compare string literals as you say.

Currently im trying to get the game to replay... at the beginging of my code I have:


and near the end My replay code is:


I realy cannot see how to get it to loop back ground to the beginging though

 

[Rossmac]

your call to method play() must be followed by a semi-colon to make it a legal statement.

ie.

play();

 

[Una]

Best way to do is is to have a game loop.

while (!gameOver)
{
// Do some stuff
}

Then when its game over you just set gameOver to true and your program terminates.

and obviously your missing a semicolon on play();

Added ; But now I cant launch the program at all

That could be usefull save the fact that i want the game to replay, not terminate if the user selects replay

 

[jcb33]

It does not bring up an error just sits there staring at me, not loading

Yeah then you have a switch/if statement somelogic inside your loop.

Different methods to display different bits of text....

One method that restarts the game etc...

When you want to replay you just call your play method again.

I have no idea how I would go about that :/
