BCEL and IfThenElse construct

Hi,

I have some piece of code which I want to convert to Java using the
BCEL. Methodcalls etc work fine but now I am stuck with the "if then
else" structure.

Can someone please post an example for something simple like:

if y > x then
Foo()
else
Bar()

TIA!

Best regards,

It is unclear what exactly you want to convert to java. If you meant to
write java bytecode, then see below.

> Bar()

Bytecode:

    ...
    iload_y
    iload_x
IF:    if_icmple ELSE
    invokexxx Foo
    goto END_IF
ELSE:
    invokexxx Bar
END_IF:    ...
