JAVA里面从键盘输入怎么才能接收double类型的 输入类 ScannerScanner scan=new Scanner(System.in)；double d=scan.nextDouble()；用d来接收键盘上的double类型
Java中怎样定义一个方法来接收键盘输入的数 importjava.util.*；publicclassCount{/*@paramargs*/publicstaticvoidmain(String[]args){Scannersc=newScanner(System.in)；获取键盘输入inta=sc.nextInt()；intb=sc.nextInt()；intc=sc.nextInt()；System.out.println(\"由大到小的顺序是：\")；if(a>；b){if(b>；c){System.out.println(a+\"\"+b+\"\"+c)；}else{System.out.println(a+\"\"+c+\"\"+b)；}}elseif(b>；a){if(a>；c){System.out.println(b+\"\"+a+\"\"+c)；}else{System.out.println(b+\"\"+c+\"\"+a)；}}elseif(c>；a){if(a>；b){System.out.println(c+\"\"+a+\"\"+b)；}else{System.out.println(c+\"\"+b+\"\"+a)；}}}}
Java如何从键盘接收数据 import java.util.*；public static void main(String[]args){ Scanner sc=new Scanner(System.in))；String ss=sc.nextLine()；}。
