1〕程序清单及注释
importjava.util.*;
publicclassStudent
{
publicstaticvoidmain(Stringargs[])
{
Scannerin=newScanner(System.in);//构造Scanner对象，并与“标准输入流”System.in关联
System.out.println(学生姓名，学号，专业);
Stringname=in.next();//输入学生姓名
intnum=in.nextInt();//输入学号
Stringmajor=in.next();//输入专业
System.out.println(学生姓名：+name+学号：+num+专业：+major);//输出学生姓名，学号，专业
