### Question:
IntInsnNode extends AbstractInsnNode { public void setOpcode(final int opcode) { this.opcode = opcode; } IntInsnNode(final int opcode, final int operand); void setOpcode(final int opcode); @Override int getType(); @Override void accept(final MethodVisitor methodVisitor); @Override AbstractInsnNode clone(final Map<LabelNode, LabelNode> clonedLabels); public int operand; }### Answer:
@Test public void testSetOpcode() { IntInsnNode intInsnNode = new IntInsnNode(Opcodes.BIPUSH, 0); intInsnNode.setOpcode(Opcodes.SIPUSH); assertEquals(Opcodes.SIPUSH, intInsnNode.getOpcode()); }
