Hi everyone, I'm starting to study AOP in Java and I would like an advice. ​ I’m currently working on a Job from a Spring Batch application, in this Job I will do a select on the database and find X records, these records will have a STEP that represents in which step inside the Job flow the record is currently at and the Job will have Y steps that cannot be skipped (in order to end the job successfully the record must pass every single step). ​ At the moment I’m using a SWITCH without a break based on the record STEP so it “starts” when the record step is matched and end at the final step.

In dual monitor setup, Java returns different usable screen bounds for Windows 10 and11. In Windows 10, Java returns unscaled usable bounds for the X and Y coordinates of a second display, and in Windows 11 it returns scaled bounds for X and Y coordinates. submitted by /u/_dk7 [visit reddit] [comments ..read more

Help! My task is to create a quiz view player. My problem is displaying the scores in the 'RESULTS' JFrame from the 'QUIZ' JFrame. ​ My code for the 'QUIZ' JFrame is: RESULTS sc1 = new RESULTS(); RESULTS.txt_score1.setText(String.valueOf(score1)); sc1.setVisible(true); new TRUEORFALSE().setVisible(true); this.dispose(); ​ It shows on the 'RESULTS' JFrame but, it only shows for one second; it does not stay. How can I make it stay? ​ Note: this Quiz View Player has three sets of a quiz, so when the scores show up in the 'RESULTS' JFrame, I still have to add those scores for the total score. It ..read more

Doing a micronaut application and all these different libraries for data fetching from a db is just melting my brain. I have it connected to a postgres db and are trying to make a simple join to get each EntityA as a property in EntityB based on the same column value (an ID). They do not hold actual row ids to each other in the db. Pretty much a simple "where id is the same as this id from this table". From the documentation I get a bunch of annotations. Some from micronaut data, some from JDBC, some from JPA and Hibernate, and to be honest. This seems like a damn frankenstein monster where t ..read more

I was trying to follow some youtube guide ("Java full Course for free" by "Bro code"). I created new project and class for it. But when i try to compile and run I only see error like ​ "Error: Could not find or load main class projekt.Main Caused by: java.lang.ClassNotFoundException: projekt.Main" or "Unbound classpath container: 'JRE System Library [JavaSE-19]' in project 'project' ​ Im very shy asking for help.

Write a java program that takes 3 inputs: • A strings, consisting of only digits. ( You don't need to check that. Assume the user enters it right) • A number p, representing a patch number • A number d, representing a divisor. Your program should process the string in patches of size p, and checks if all patches are divisible by d or not. If so, it outputs true, otherwise it outputs false. PS. You are not allowed to use substring() method. Examples: Case S="846738" p=2d=2 Output: False. S="846738" p=3 d=2 Output: True. 5="846738" p=5 d=2 Output: Incompatible here's my code which i know is wro ..read more

here's the question : Write a program that takes two strings s1 and s2 as inputs and checks whether string s1 is a substring in string s2. Example: s1 = "abc" s2 = "ababc" Output: true s1 = "a" s2 = "ababc" Output: true s1 = "abc" s2 = "ababa" Output: false here's my code(there are no syntax errors however it keeps on printing false in all cases) import java.util.*; public class Main{ public static void main (String[] args) { Scanner sc = new Scanner(System.in); System.out.print("enter the first string: "); String s1 = sc.nextLine(); System.out.print("enter the second string: "); String s2 ..read more
