(1) FileInputStream
(2) char buf;
(3) (char) fis1.read()
(4) while ((buf = (char) fis2.read()) > 0) System.out.print((char) buf);
fis1.close();
(5)catch (FileNotFoundException e)
你题目抄的有点问题 附上可执行源码
public class SequenceInputStreamDemo {
public static void main(String[] args) {
// _______(1)___________fis1,fis2;
FileInputStream fis1,fis2;
try {
fis1 = new FileInputStream("prog1.java");
fis2 = new FileInputStream("prog2.java");
// _________(2)___________;
char buf;
// while((buf=________(3)_________)>0) System.out.print((char)buf);
while ((buf = (char) fis1.read()) > 0) System.out.print((char) buf);
// ________(4)_______;
while ((buf = (char) fis2.read()) > 0) System.out.print((char) buf);
fis1.close();
fis2.close();
// }________(5)_________{
} catch (FileNotFoundException e) {
System.out.println(e);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

(1) 什么也不填
(2) super();
(3) 什么也不填
(4) .indexOf(" ");
(5)i > 0
可执行代码：
public class Name {
private String useName;
private String useS;
// public _______(1)Name{
public Name() {
// _______(2) useName =”whatever”; useS=”whatever”;}
super();
useName = "whatever";
useS = "whatever";
}
// public _______(3)Name (String s)
public Name(String s) {
// {int i=s._______(4)___________;//搜索空格
int i = s.indexOf(" ");
// if(_______(5)___________){
if (i > 0) {
useName = s.substring(0,i);
useS = s.substring(i + 1);
}
}
}
