Integer还实现了Comparable接口,因此也具备了比较对象大小的能力,其compareTo()方法具体实现如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 publicintcompareTo(Integer anotherInteger){returncompare(this.value,anotherInteger.value);}publicstaticintcompare(int x,int y){return(x<y)?-1:((x==y)?

In addition, this class provides several methods for converting an int to a String and a String to an int, as well as other constants and methods useful when dealing with an int. Implementation note: The implementations of the "bit twiddling" methods (such as highestOneBit and numberOfTraili...
