用java 从键盘输入3个整数,分别赋给整数变量a b c 然后将输入的整数按照从小到大的顺序放在变量abc中,并 2L你好夸张!把下面代码放到main()方法中Scanner s=new Scanner(System.in);System.out.println(\"请输入a的值:\");int a=s.nextInt();System.out.println(\"请输入b的值:\");int b=s.nextInt();System.out.println(\"请输入c的值:\");int c=s.nextInt();int x=0;if(a>;b){x=a;a=b;b=x;}if(a>;c){x=a;a=c;c=x;}if(b>;c){x=b;b=c;c=x;}System.out.println(a+\",\"+b+\",\"+c);用java 2L你好夸张。把下面代码放到main()方法中Scanner s=new Scanner(System.in);System.out.println(\"请输入a的值:\");int a=s.nextInt();System.out.println(\"请输入b的值:\");int b=s.nextInt();System.out.println(\"请.Java中怎样接受用户输入然后把值赋给一个变量 我用的是JCreator.我倒是知道System.out.println()是输出.那我以为接受用户输入是System.in.read(),结果不行。.JAVA声明了int变量A,想从键盘输入一个值,赋给A,请问语句怎么写? import java.io.*;public class class-name{public statlc void main(string args[])throws IOException{ BufferedReader buf;string A;buf=(new BufferedReader(new inputStreamReader(System.in)));A=buf.readline();}}由键盘输入的数据不论是文字还是数字,java都视为字符串,不明白的地方可以再问,这是我刚刚输入的,给个辛苦分吧。Java中怎么把用户输入Scanner的值赋值给另一个int 变量? import java.util.Scanner;public class Test {public static void main(String[]args){百/创建读入流度Scanner scan=new Scanner(System.in);获取下一个输入专的int 数值回车结束,输入其它类型会报错int n=scan.nextInt();输出输入的值属System.out.println(\"输入的数:\"+n);}}怎么实现java日期的输入?并且能将输入值分别赋给变量year month,输出时按照yyy-month格式输出,谢谢 import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;public class CalendarDemo {public static void main(String[]args){formatData(2013,12,33);formatData(new Date());formatData(new Date(),\"yyyy-MM\");}public static void formatData(int year,int month,int date){Calendar calendar=Calendar.getInstance();calendar.set(year,month,date);print(calendar);}public static void formatData(Date date){Calendar calendar=Calendar.getInstance();calendar.setTime(date);calendar.add(Calendar.MONTH,1);print(calendar);}public static void formatData(Date date,String format){SimpleDateFormat sim=new SimpleDateFormat(format);String result=sim.format(date);System.out.println(result);}public static void print(Calendar calendar){System.out.println(calendar.get(Calendar.YEAR)+\"-(calendar.get(Calendar.MONTH)(Calendar.MONTH):calendar.get(Calendar.MONTH)));}}Java中如何输入一个整型值,并把它赋值给一个变量 import java.util.Scanner;public class Test {public static void main(String args[]){Scanner in=new Scanner(System.in);System.out.println(\"请输入一个整数\");int a;a=in.nextInt();System.out.println(\"a=\"+a);}}Java中怎样接受用户输入然后把值赋给一个变量 BufferedReader br=new BufferedReader(new InputStreamReader(System.in));System.out.print(\"请输入用户名:\");String userName=br.readLine();System.out.print(\"请输入密码:\");String pass=br.readLine();
