There are several ways to debug Java code. When developing, you can use the tools available in your IDE or debugger. Once the application is deployed to production, you can capture the logs or use an error monitoring solution. Let’s explore each of these ways in more detail. Debugging wi...

In order to debug from your device, we need to rely on adb logcat. Logcat is a command-line tool that dumps a log of system messages, including stack traces when the device throws an error and messages that you have written from your app with the Log clas...
something in the packagecom.myproject(it’s on the 3rd line here), then scan to the end of the line to see where the code is (MyProject.java:17). That line will contain some code that callsFraction.getFraction. This is the starting point for investigation: What is passed togetFraction...

Decompiling Java code can help turn the tide when debugging critical problems. This is a beginners overview of how Java decompiling works to debug Java.
The collection framework includes another challenge when debugging: erasures. In Java one would expect code like this to work: List<MyObject>myList=newArrayList<>(); Then the log might look like this: Theproperty value of the first element is{myList.get(0).getProperty()} ...
Virtual Machine (JVM) or by Java code. While errors and exceptions are similar in that they both indicate that something unexpected has occurred, there are some differences between the two - while exceptions can be recovered, errors cannot be done so and they just put a sudden stop to every...
When a user identifies a defect, developers need to debug the code and trace the errorback to the root cause. Otherwise, the bug fix might only repair a symptom rather than fixing the bug completely. 2. Replicate the bug in a test or development environment ...
