scala 调用 java cannot resolve overloaded method 当在Scala中调用Java代码时出现"cannotresolveoverloadedmethod"错误时，通常是因为在Java类中存在多个同名方法但参数类型不同，而Scala在解析方法时无法确定要调用哪个方法。 要解决这个问题，你可以尝试以下几种方法： 1.显式地指定参数类型：在调用Java方法时，明确...

In our experience, the JVM JIT compiler cannot always inline private field accessor methods, and thus it is safer to use private[this] to ensure no virtual method call for accessing a field. class MyClass { private val field1 = ... private[this] val field2 = ... def perfSensitive...
private[this] generates a field, rather than creating an accessor method. In our experience, the JVM JIT compiler cannot always inline private field accessor methods, and thus it is safer to use private[this] to ensure no virtual method call for accessing a field. class MyClass { private ...
