The -enableassertions (-ea) solution applies to all class loaders and to technique classes (which don’t have a category loader). There’s a person exception to this rule: If the choice is supplied with no arguments, then it doesn’t implement to method lessons. This causes it to be very easy to permit assertions in all classes apart from process classes. The -enablesystemassertions option supplies a separate switch to help assertions in all system courses.

Sets the utmost bytecode measurement (in bytes) of a method to get inlined. Append the letter k or K to indicate kilobytes, m or M to point megabytes, or g or G to indicate gigabytes. By default, the most bytecode dimension is set to 35 bytes:
print java/lang/String toString Should you’re using commands with the JIT compiler to carry out on solutions, then see the -XX:CompileCommand option.
Sets the initial and greatest dimensions (in bytes) of your heap for that youthful generation (nursery). Append the letter k or K to indicate kilobytes, m or M to point megabytes, or g or G to point gigabytes. The youthful technology area in the heap is useful for new objects. GC is done During this region much more normally than in other locations. If the dimensions with the younger era is simply too tiny, then lots of minimal garbage collections are carried out.
