The conversion of adata typewhich is carried out automatically by the compiler without programmer intervention is called the implicit type conversion. When two variables of different data types are involved in the same expression, theJavacompiler uses built-in library functions to trans- form the var...

隐式转换(implicit conversion) 回顾一下前面说到的小例子,让字符串能够带分隔符打印: "hello,world"printWithSeperator"*" 此时,Scala编译器尝试从当前的表达式作用域范围中寻找能够将String转换成一个具有printWithSeperator 函数的对象。 为此,我们提供一个PrintOps的trait,有一个printWithSeperator函数: ...
