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...
自动转换为比自身表述范围大的类型。 具体细节请参见官方文档: docs.oracle.com/javase/specs/jls/se7/html/jls-5.html#jls-5.1.4 所以对于 (int 5) / (double 3.0), double 是 64 位 ,int 是 32 位,所以计算的时候会自动将 int 5 转换成 double 5.0, 然后再计算,所以结果便是 double 类型。 明白...

In the above example, we have used the parseInt() method of the Integer class to convert the string variables into the int. Here, Integer is a wrapper class in Java. To learn more, visit the Java Wrapper Class. Note: The string variables should represent the int values. Otherwise the co...

Thus, in the above example we find that the output result is 12 because in the result expression the user has explicitly defined the operands (variables) as integer data type. Hence, there is no implicit conversion of data type by the compiler....
