Integer继承了抽象类Number,并实现了它的下列方法:byteValue()shortValue()intValue()longValue()floatValue()doubleValue(),将int转换为其他基本类型的值,实现方法都是强转。 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 A...
可以用compareTo进行比较并且Integer对象只能和Integer类型的对象进行比较 * 3.Integer类继承了Number,所以该类可以调用longValue、floatValue、doubleValue等系列方法返回对应的类型的值 */ public final class Integer extends Number implements Comparable<Integer> { /** * A constant holding the minimum value an ...
String str2 = Integer.toBinaryString(num);// 获取数字的二进制表示 String str3 = Integer.toHexString(num);// 获取数字的十六进制表示 String str4 = Integer.toOctalString(num);// 获取数字的八进制表示 String str5 = Integer.toString(num, 15);// 获取数字的十五进制表示 System.out.println("456...
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...
If the value p being boxed is true, false, a byte, an ASCII character, or an integer or short number between -127 and 128, then let r1 and r2 be the results of any two boxing conversions of p. It is always the case that r1 == r2. ...
