    Default Simple help in Java !!

    I wrote this simple piece of code to find the number in the given array of Integers.The program works fine although it shows a couple of errors when i modify it a little bit.
    public class DemoLabel{
    	public static void main(String [] args){
    		int[][] arrofInts={
    		int searchFor=12;
    		int i;
    		int j=0;
    		boolean foundIt=false;
    			System.out.println("HELLO");//Shows error
    						continue search;
    			System.out.println("The number " + searchFor+" was found at " + i+","+j);
    			System.out.println("The number was not  found ");
    	public static void disp(int i, int j,int searchFor){
    		System.out.println("The number "+searchFor+" is at the location "+i+" , "+j);

    In the disp() method,Suppose i only want to pass two arguments i.e disp(i,j) given that searchFor variable is visible in the entire class but when i use disp(i,j) i get the following error DemoLabel.java:38: error: cannot find symbol System.out.println("The number "+searchFor+" is at the location"+i+" , "+j);
    symbol: variable searchFor
    location: class DemoLabel

    So i decided to declare the
    int searchFor
     public int searchFor
    but the compiler threw another error saying that it was a Illegal start of expression

    Also,when i add a SOP line after the label search: it shows the error DemoLabel.java:25: error: undefined label: search
    continue search;

    Although i got the program to work it would be helpful if i could understand why it doesn't work with the modifications.

    Illegal start of expression
    Variables in methods can't be accessed from outside of the method. public is not valid there.
    error: undefined label: search
    I think labels MUST be on loop statements like for and while. Not just close to them
    If you don't understand my answer, don't ignore it, ask a question.
