Why isn't the Boolean value recognized?

public class HelloWorld {

    public static void main(string[] args) {
        boolean found;
        String[] caseArray = new caseArray {
            "apple", "orange", "mango", "pineapple"
        } ;
        for (int i = 0; i < caseArray.length; i++) {
            if (caseArray[i].equals("pineapple")) {
                found = true;
                break;
            } else {
                found = false;
            }
        }
        if (found == true) {
            System.out.println("product found");
            break;
        } else {
            System.out.print("product not found");
            break;
        }
    }
}

In the above code I would like to return found = true when the for loop searches pineapple in the array. If found is equal to true I would like it to print "product found", if found = false I would like it to print "product not found".

I don't think this will compile, because of your uninitialized boolean variable. In the case of a 0 length array, the found boolean will never get initialed, and Java won't let you do that

public class HelloWorld{

    public static void main(string [] args){

    boolean found = false;

    String [] caseArray = new caseArray{"apple", "orange", "mango", "pineapple" };

    for(int i = 0; i< caseArray.length; i++){

                                    if(caseArray[i].equals(pineapple)){

                                        found = true;
                                        break;
                                    } else{

                                        found = false;
                                    }

                                }

                                if(found == true){

                                    System.out.println("product found");
                                    break;

                                } else {
                                    System.out.print("product not found");
                                    break;
                                }    

    }
}

Your code does not follow the java grammar correctly.
This will work.

public class HelloWorld{
    public static void main(String[] args){
        boolean found = false;
        String[] caseArray = new String[]{"apple", "orange", "mango", "pineapple" };

        for(int i = 0; i< caseArray.length; i++) {
            if(caseArray[i].equals("pineapple")) {
                found = true;
                break;
            }
        }
        
        if(found == true) {
            System.out.println("product found");
        } else {
            System.out.print("product not found");
        }
    }
}

On your post, those are not following the grammar.
First, on your code

public static void main(string[] args) {

On above code, args is string[] (small s first) and it should be uppercase. (String[])

Second, on your code

String[] caseArray = new caseArray{...

Here, caseArray is not the java type and it should be updated as follows.

String[] caseArray = new String[]{...

And third, I have set the initial value of found to false and if we use like this, no need to set found = false in for query.

First of all there are couple of syntax issue with this code.

• the String array initialization is wrong

  String [] caseArray = new caseArray{"apple", "orange", "mango", "pineapple" };
  

• in equals() check String has a syntax error

  if(caseArray[i].equals(pineapple)){
  

• didn't initialize the boolean but you try to use that variable later.

• break; keyword is used outside a loop in an if condition.

I have corrected the syntax so that you can execute it.

public class Test {
	public static void main(String[] args) {
		try {
			boolean found = false;
			String[] caseArray = { "apple", "orange", "mango", "pineapple" };
			for (int i = 0; i < caseArray.length; i++) {
				if (caseArray[i].equals("pineapple")) {
					found = true;
					break;
				}
			}

			if (found) {
				System.out.println("product found");
				// break;
			} else {
				System.out.print("product not found");
				// break;
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

Output:

product found
