RE: Pushing Integer(), getting int, how to deal with?

You're going to need to make an Integer yourself. 

 

mv.visitFieldInsn(GETSTATIC, "java/lang/System", "err",
"Ljava/io/PrintStream;");

mv.visitLdcInsn(new Integer(10));

mv.visitMethodInsn(INVOKESTATIC, "java/lang/Integer", "valueOf",
"(I)Ljava/lang/Integer;");

mv.visitMethodInsn(INVOKEVIRTUAL, "java/io/PrintStream", "println",
"(Ljava/lang/Object;)V");

Subject: [asm] Pushing Integer(), getting int, how to deal with?

 

I have this small section of code that is causing me problems:

        mw.visitFieldInsn(GETSTATIC,
                  "java/lang/System",
                  "out",
                  "Ljava/io/PrintStream;");
        mw.visitLdcInsn(new Integer(10));
        mw.visitMethodInsn(INVOKEVIRTUAL,
                  "java/io/PrintStream",
                  "println",
                  "(Ljava/lang/Object;)V");

How can I handle this situation? This is not the case of what my real code
looks like, but I broke the problem down into these three lines trying to
solve the problem.
