compareTo方法是用来比较两个字符的大小顺序的方法,返回值为int类型,如果两个字符相等则返回0,大于则返回正数,小于则返回负数。下面是一个示例: charc1='a';charc2='b';intresult=Character.toString(c1).compareTo(Character.toString(c2));if(result==0){System.out.println("c1和c2相等");}elseif(result<...

1.像String、包装类等实现了Comparable接口,重写了compareTo(obj)方法,给出了比较两个对象大小的方式。 2.像String、包装类重写compareTo()方法以后,进行了从小到大的排列 3. 重写compareTo(obj)的规则: 如果当前对象this大于形参对象obj,则返回正整数, 如果当前对象this小于形参对象obj,则返回负整数, 如果当前对象...

3. 使用Character类的compare方法 除了使用比较运算符,Java还提供了一个名为Character的封装类,其中包括compare方法,该方法可以用来比较两个char值。其实这个方法是将字符转换为整数后进行比较。 AI检测代码解析 importjava.util.Arrays;publicclassCharComparison{publicstaticvoidmain(String[]args){char[]charArray={'c...
