First change the method signature to return a value: public static boolean checkUSPASS(String a,String b) Then return a value from within the method: return true; or: return false; Note that all code paths must return some value. So you have this in your try block: if (rs.next()) { return true; } else { return false; … Read more

If you want it to be an array, it should be something like this: “claim”: [ “date”: “2015-08-06”, “comments”: “Some comments” ] (notice the [ ] instead of { }) If it’s meant to be an object, then the code should read: JSONObject claims = c.getJSONObject(TAG_CLAIM); 4 … Read more
I could not post it to comment section. Please see below: List<Integer> integers = Arrays.asList(1, 2, 3, 4); int i = 0; StringBuilder sb = new StringBuilder(“[“); for (int value : integers) { sb.append((i == 0) ? “” : (i % 2 == 0 ? “,” : “:”)).append(value); i++; } sb.append(“]”); System.out.println(sb.toString()); Output is: [1:2,3:4] … Read more
Type is an instance of the String object, it has the method String#equals(…) and that method returns a boolean… “!” this is the negation opeator and inverts any boolean value… so !type.equals(“auto”) is a boolean condition as result from comparing whether the String var with the name type has the value “auto” . solved What … Read more

Okay several possibilities: Instantiate A: A a=new A(); a.xyz(); (you do not want this) Heredity: public class B extends A {…} and public class A extends ZZZZZ{…} so you can still extend ZZZZZ; Interface: public interface A{…} public class B extends ZZZZZ implements A{…} Static Method: public class A{ public static void xyz() { System.out.println(“hello”); … Read more
You always add your profit to hardcoded 5000 instead of saving your current amount and adding it to that. Try that: // Define this as global variable int cash = 5000 // When win: String text = spinnerData.getSelectedItem().toString(); //i get data from spinner int temp = Integer.parseInt(text); //then parse it to Int int temp2 = … Read more
Basically, that code does this: 1) Initializes temp array with 100 positions (all set to 0); 2) Iterates over data array and increments the value relative to the index of the data array value it’s processing. Take this example: int[] data = {23,11,10,23,5}; temp[data[0]] += 1 temp[23] += 1 temp[23] = temp[23] + 1 = … Read more

a[i] = Double.toString(a[i]); The left-hand side, a[i], is a variable of type double. The right-hand side, Double.toString(a[i]), is a value of type String. So you’re trying to assign a String to a variable of type double, hence the error: you can’t store a String in a variable of type double, because a String is not … Read more
