For example : make a method that returns 3.
the instructions you're looking for are
with what visit call ?
mv.visitIntInsn();
?
first: visitCode to start the code section
then: visitLdcInsn(3) for
ldc 3, followed by visitInsn(Opcodes.IRETURN) for ireturn
dont forget to set the correct method return type in the descriptor, should be (whateverArgsYouWant)I
forgot: visitEnd afterwardsOk thank you very much!
