通过Scanner 类的 next() 与 nextLine() 方法获取输入的字符串,在读取前我们一般需要 使用 hasNext 与 hasNextLine 判断是否还有输入的数据: importjava.util.*;publicclasstest {publicstaticvoidmain(String[] args) { Scanner scan1=newScanner(System.in); System.out.println("next方式接收:");if(scan1.ha...

它的大体实现结构就是: JAVA 使用 jni 调用c++实现的StringTable的intern方法,StringTable的intern方法跟Java中的HashMap的实现是差不多的, 只是不能自动扩容。默认大小是1009。 要注意的是,String的String Pool是一个固定大小的Hashtable,默认值大小长度是1009,如果放进String Pool的String非常多,就会造成Hash冲突严重...
java编程实现:从键盘任意输入一个数,判断这个数是不是7的倍数.import java.util.Scanner;class test7 {public static void main(String args[]){Scanner scan=new Scanner(System.in);int i;i=scan.nextInt();if (i%7==0)System.out.println
