类Java |合成是什么意思？

Question

我正在浏览java{}（反编译），发现了一些吸引我眼球的东西

@Override
public boolean isSynthetic() {
    return super.isSynthetic();
}

“合成”。这是什么意思

它在代码中可用吗

既然我在Method类中发现了这一点，我想知道，整个方法是可以“合成的”，还是它包含合成的东西

提前谢谢

不是What is the meaning of “static synthetic”?的副本

Answer 1

Any constructs introduced by the compiler that do not have a corresponding construct in the source code must be marked as synthetic, except for default constructors and the class initialization method.
