while(br.read()!=-1)
{
System.out.println(br.readLine());

Answer 1

改成这样试一下吧:
File f=new File("E:/JAVA/File/myFile/1.txt");
BufferedReader br=new BufferedReader(new FileReader(f));
                           String s,s1 = new String();
while((s=br.read())!=-1)
{
s1+=s+"\n";
}                       
                           System.out.println(s1);

Answer 2

对不起,是这样,刚才函数名写错了:
File f=new File("E:/JAVA/File/myFile/1.txt");
BufferedReader br=new BufferedReader(new FileReader(f));
                           String s,s1 = new String();
while((s=br.readLine())!=-1)
{
s1+=s+"\n";
}                       
                           System.out.println(s1);
