JavaEdit
Java is an object-oriented programming language.
Things I don’t like about Java
- It’s verbose:
# Java
System.out.println("Hello, world!");
# C
printf("Hello, world!\n");
# Ruby
puts "Hello, world!"
- It’s slow:
# Java
System.out.println("Hello, world!");
# C
printf("Hello, world!\n");
# Ruby
puts "Hello, world!"
As a concrete example, ANTLR parsers generated using the Java target run about half as fast as those generated using the C language target.
- It’s bloated:
As an example, the ANTLRWorks instance I am currently running is currently taking up 114 MB of real memory (608 MB of virtual memory) and has 20 threads and 956 Mach ports. For comparison, the running copy of BBEdit is using 34 MB of real memory (263 MB virtual), and has only 4 threads and 113 Mach ports.
As another example, a just-launched copy of Azureus, when idle, consumes 53 MB of real memory (577 MB virtual) and spawns an astonishing 46 threads, with 877 Mach ports.
