Java 14 New Features | Helpful Null Pointer Exception in java JDK 14| Java Beam
Null Pointer Exceptions are a nightmare for any java developer. Before java 14, it was tricky to debug the infamous NPEs(Null Pointer Exception).
Developers had to fall onto other debugging tools or manually figure the variable/method that was null since the stack trace would only show the line number.
Before Java 14:
String name = a.getBlog().getAuthor()
//Stacktrace
Exception in thread "main" java.lang.NullPointerException at NullPointerExample.main(NullPointerExample.java:5)
Java 14 introduced a new JVM feature, which gives better insights with a more descriptive stack as shown below:
Exception in thread "main"
java.lang.NullPointerException: Cannot invoke "Blog.getAuthor()" because the return value of "Article.getBlog()" is null at NullPointerExample.main(NullPointerExample.java:4)
Note: The above feature is not a language feature. It’s an enhancement in the runtime environment.
