以下代码实现读取五条数据分别赋值给s1,s2,s3,s4,s5.问题是得到的几条数据都相同，都是s5.
try{
BufferedReader br = new BufferedReader(new FileReader("paiming.txt"));
String line = null;
//StringBuilder pmsb = new StringBuilder();
String s1 = null;
String s2 = null;
String s3 = null;
String s4 = null;
String s5 = null;
int n = 1;
while((line = br.readLine())!=null && n<=5){
switch (n){
case 1:
s1=line;
case 2:
s2=line;
case 3:
s3=line;
case 4:
s4=line;
case 5:
s5=line;
}
}
br.close();
