java - How to get fat16 or fat32 or ntfs filesystem on Linux -

i tried code:

    try {         process p = runtime.getruntime().exec("df -t");         bufferedreader in = new bufferedreader(new inputstreamreader(p.getinputstream()));         string line = null;         while ((line = in.readline()) != null) {             string[] values = line.split(" ");             (string str : values) {                 system.out.println(str);                 if (str.equals("ntfs")){                     system.out.println("ntfs");                 }             }             //system.out.println(line);         }         in.close();     } catch (ioexception e) {         e.printstacktrace();     } 

but isn write ntfs , how can work fine? or have use other command? want check filesystem use. df -t:

  filesystem                       1k-blocks     used available use% mounted on   /dev/mapper/centos_vjanurik-root  52403200 42261280  10141920  81% /   devtmpfs                           3894660        0   3894660   0% /dev   tmpfs                              3904524     4892   3899632   1% /dev/shm   tmpfs                              3904524     9168   3895356   1% /run   tmpfs                              3904524        0   3904524   0% /sys/fs/cgroup   /dev/mapper/centos_vjanurik-home  56235184 29428876  26806308  53% /home   /dev/sda1                           508588   107384    401204  22% /boot 

on system df -t outputs file system type in lowercase. comparing against "ntfs" .... uppercase.

also, output have shown doesn't appear output regular linux df -t ... because doesn't have type column.
