My handlers don't work smooth.How can i fix it? - switch-statement

Question

Hello everyone i try to get commands from txt file and I want to run these commands in order for a certain period of time.I can get the commands from the txt file correctly but when I want to do these commands using handlers for a certain period of time but there is a problem.The problem is handlers work together,the other Handler comes into play before the first Handler's time expires.When i did that with same runnable it did same thing.
My txt file looks like:
Ileri,5,1 /n
Sol,10,1 /n -->10 is operation time 1 is The number of repetitions.
Sag,5,1 /n
Geri,10,1 /n
My output:
I/System.out: Ileri
6000
1
I/System.out: Sol
11000
1
I/System.out: Sag
6000
1
I/System.out: Geri
11000
1
I/System.out: A

I solved my problem by using thread.sleep(); and i'm writing here because someone might need my code.
start_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
timer=new Timer();
///data/data/com.example.emrecan.myapplication/files/komutlar.txt

String saniye1;
String tekrar;
int i=0,j=0,c=0,d=0;
ArrayList<String> listS=new ArrayList<String>();
try {
Scanner s=new Scanner(new File("/data/data/com.example.emrecan.myapplication/files/komutlar.txt"));
while(s.hasNextLine())
{
listS.add(s.nextLine());
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
String[] line2=new String[100];
for(String str:listS)
{
String[] line=str.split(",");
line2[c]=line[i];
line2[c+1]=line[i+1];
line2[c+2]=line[i+2];
c=c+3;
}
String [] line3=new String[c+2];
while(d<c)
{
line3[d]=line2[d];
d=d+1;
}
d=0;
tekrar=line3[2];
int tekrar1=Integer.parseInt(tekrar);
while(d<tekrar1)
{
while(j<=c-2) {
yon = line3[j];
saniye1 = line3[j + 1];
sure1 = Long.parseLong(saniye1);
sure1 = sure1 * 1000;
//sure1 = sure1 + 1000;
System.out.println(yon);
System.out.println(sure1);
System.out.println(tekrar1);
e = 0;
while (sure1>0)
