Question

写一个java方法读取dat文件中的数据

.dat
[31.812229,119.98992][31.653584,120.75250]
去掉[,] 并用double类型数据接收

如double lat = 31.812229
double lon = 119.98992

Answer 1

String[] data = dat.sqlit("[],");
double[] d = new double[4];
for(int i = 0,int j=0;i<data.length,j<4;i++){
try{
d[j]=Double.valueOf(data[i])

j++;

}catch(Exception e){
continue;

}

}

貌似错的啊，你能写的完整一点吗，谢谢...

追答

String str = "[31.812229,119.98992][31.653584,120.75250]";
str=str.replace("[",",").replace("]",",");
String[] data = str.trim().split(",");
double[] d = new double[4];
int j=0;
for(int i = 0;(i<data.length)&&j<4;i++){
try{
d[j]=Double.valueOf(data[i].equals("")?null:data[i]);
j++;
}catch(Exception e){
continue;
}
}
至于把.dat读成String用BufferedReader的readline()就不说了

能帮我整理下吗。我小白....
