The comparison is based on the Unicode value of each character in the strings. The method returns 0 if the string is equal to the other string. A value less than 0 is returned if the string is less than the othe

Java编程过程中,Integer对象(或其它继承自Number类的包装类对象)使用Number包装类内置的compareTo()方法来比较调用对象和参数之间的大小的时候,Java的集成开发环境IDE或编译器给出了提示:The method compareTo(Integer) in the type Integer is not applicable for the arguments (Float),后类似的提示,这是怎么回事呢?
String.compareTo是少数非常重要的方法之一,为此虚拟机工程师专门为它手写了汇编风格的代码(译注:这些代码会被汇编器转换为机器代码,所以实际上是指用汇编风格写机器代码) # {method} 'compare' '(Ljava/lang/String;Ljava/lang/String;)I' in 'Test' # parm0: rsi:rsi = 'java/lang/String' # parm1: rd...

(2)ReturnType method(byte x, double y) { return (short)x/y*2; } 返回类型应该是double类型。因为x强制转换为short类型后,除以double类型的y,结果会自动升级为double类型。 注:强制转换比四级运算的优先级高。 二.强制类型转换 使用强制类型转换时,可能会失去精度,所以在进行强制类型转换之前,一定要注意转换...

The result is a positive integer if this String object lexicographically follows the argument string.The result is zero if the strings are equal; compareTo returns 0 exactly when the equals(Object) method would return true.This is the definition of lexicographic ordering.If two strings are ...
