关于java IO 流的问题

为什么从屏幕读取的时候跳着读？
例如：输入abc，却只打印出来b.
Read 是怎样读取的字符?

Java code:

import java.io.*;

public class TestIO {
public static void main(String[] args) throws IOException{
BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Please enter some characters:");
while(stdin.read()!=(-1)){
char c;
c=(char)stdin.read();
System.out.println(c);

}
System.out.println("读取完毕!");
}
}

自己先顶下

你都已经声明 C为CHAR了  那CHar 肯定只能是一个字符的阿

---

stdin.read()!=(-1) 这里已经读出第一个字符 不是吗?

---

Java code:

public static void main(String[] args) throws IOException{
BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Please enter some characters:");
String str;
if((str=stdin.readLine())!=null){
System.out.println(str);
}
System.out.println("读取完毕!");
stdin.close();
}
