Java String类 compareTo() 方法用于两种方式的比较: 字符串与对象进行比较。 按字典顺序比较两个字符串。 语法 intcompareTo(Objecto)或intcompareTo(StringanotherString) 参数 o-- 要比较的对象。 anotherString-- 要比较的字符串。 返回值 返回值是整型,它是先比较对应字符的大小(ASCII码顺序),如果第一个字...
compare为什么返回int java java compare返回值 Comparator VS Comparable 1. Comparator 1.1 对一维数组进行排序 1.2 对二维数组进行排序 1.3 对对象数组进行排序 2. Comparable 3. 二者区别 1. Comparator 通过源码发现Comparator是一个接口。 根据compare方法中的注释可以发现方法返回三种类型的值,正数、零、负数,分别...

在Java中,compareAndSwapInt是一种原子操作,用于比较并交换整数类型的值。它的定义如下: publicfinalnativebooleancompareAndSwapInt(Objectobj,longoffset,intexpect,intupdate); 1. 其中,obj是要操作的对象,offset是要操作的字段在该对象中的偏移量,expect是期望的值,update是要更新的新值。如果字段的当前值与expect...
