GetMethodID()可使未初始化的类初始化。 要获得构造函数的方法 ID,应将<init>作为方法名,同时将void(V) 作为返回类型。 参数: env:JNI 接口指针。 clazz:Java 类对象。 name:0 终结的 UTF-8 字符串中的方法名。 sig:0 终结的 UTF-8 字符串中的方法签名。
Use of this method effectively bypasses the compile-time exception checking that would otherwise be performed by the compiler. The java.lang.reflect.Constructor#newInstance(java.lang.Object...) Constructor.newInstance method avoids this problem by wrapping any exception thrown by the constructor in a ...
