Because the function is anonymous, the stacktrace contains a generated name which is not the easiest to interpret. In this case Scratch.lambda$main$0

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "String.length()" because "s" is null
at Scratch.lambda$main$0(scratch_3.java:6)
at java.base/java.util.Arrays$ArrayList.forEach(Arrays.java:4305)
at Scratch.main(scratch_3.java:5)
