this

how to solve this. as i know the code for making a function is already right. :confused:

If you're serious about needing help, you're best posting your code here with any error messages. Please click on my link to see how to use code tags though.

Edit: and also, you should know that you can't nest methods inside of each other. Post your code and I can give you the details about what this implies.

Much luck.

import javax.swing.*;
class SD 
{
	public static void main(String[] args) 
	{
		int K,G;
		String x= "ada";
		int siswa[][]= new int [5][1];

		for (int i=5;i>0 ;i-- )
		{
			for (int j=1;i>0 ;j-- )
			{
				siswa[i][j]=0;
			}
		}

		
		while (x=="ada")
		{	G=Integer.parseInt(JOptionPane.showInputDialog(null,"masukan gender 0 = Pria & 1 = Wanita"));
            K=Integer.parseInt(JOptionPane.showInputDialog(null,"masukan kelas dari 1-6"));

            siswa[K][G]=siswa[K][G]++;

            x=JOptionPane.showInputDialog(null,"apakah masih ada input??");
		}
		
					
		static int totalperkelas (int ke)
		{
            int jumlah = 0;
            jumlah = siswa[0][ke] + siswa[1][ke];
            return(jumlah);
		}}

the error message is
SD.java:29: illegal start of expression
static int totalperkelas (int ke)
^
SD.java:29: ';' expected
static int totalperkelas (int ke)
^
SD.java:29: ';' expected

Thanks. Again, your problem is that you're nesting a method within a method (we don't say "function" in Java). Specifically, the totalperkelas method is nested within the main method. The solution is to pull the totalperkelas method outside of main.

eureka.!
thankies for your help. Fubarable :)

thankies for your help. Fubarable :)

You're quite welcome. Oh, and thanks for using code tags, and a big welcome to the Java-forums.org!

errr.. fubarable 1 more k? :P

int siswa[][]= new int [5][1];
for (int i=5;i>0 ;i-- )
		{
			for (int j=1;i>0 ;j-- )
			{
				siswa[i][j]=0;
			}
		}

why it say out of bound.? as i know the looping code is alright
thanks before

Arrays go from 0 to length - 1. So for int[] foo = new int[5], we have
foo[0]
foo[1]
foo[2]
foo[3]
and
foo[4]
