1. 使用compareTo方法 Integer类提供了compareTo方法来比较两个Integer对象的大小,返回结果为负数、零或正数,分别表示前者小于、等于或大于后者。 Integera=10;Integerb=20;intresult=a.compareTo(b);if(result<0){System.out.println("a小于b");}elseif(result==0){System.out.println("a等于b");}else{Sy...
publicclassCompareIntegers{publicstaticvoidmain(String[]args){Integernum1=newInteger(10);// 创建第一个整数对象,值为10Integernum2=newInteger(5);// 创建第二个整数对象,值为5intresult=num1.compareTo(num2);// 比较两个Integer对象的大小,将结果保存在result变量中if(result<0){System.out.println("n...
以下是一个示例代码,演示了如何比较两个整数的大小:```javapublic class CompareIntegers { public static void main(String[] args) { int a = 5; int b = 10; if (a > b) { System.out.println(“a is greater than b”); } else if (a < b) { System.out.println("a is less than b"...
asList(1, 2, 3); integers.stream().map(integer -> integer + 3).forEach(System.out::println); 打印出了: 456 2.2 mapToInt/mapToLong/mapToDouble 这三个方法用于将数值流转换为 IntStream、LongStream、DoubleStream 2.2.1 IntStream、LongStream 与 DoubleStream 这三个流十分适合处理基础的数值...
(obj)取得这个默认的hash code;这种机制保证了不互相 == 的对象,其hash code一定不相同(As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects。但这句话也不完全正确,默认hash code也是存在相同的可能的,参见:http://bugs.sun....
Sum(Int32, Int32) Adds two integers together as per the + operator. ToArray<T>() (Inherited from Object) ToBinaryString(Int32) Returns a string representation of the integer argument as an unsigned integer in base 2. ToHexString(Int32) Returns a string representation of the integ...

Acoded character setis a mapping between a set of abstract characters and a set of integers. US-ASCII, ISO 8859-1, JIS X 0201, and Unicode are examples of coded character sets. Some standards have defined acharacter setto be simply a set of abstract characters without an associated assigne...
