Is there a goto statement in java?

In my android application i used goto statement to control the flow. But I received error as “Syntax error on token goto, throw expected”. Here is my code

label:
if(alc)
{
  r_code=st.nextToken();
  AlertDialog.Builder alert=new AlertDialog.Builder(Fetch.this);
  alert.setTitle(count+" records found for "+rytname.getText().toString());
  alert.setMessage("Are you sure want to search for "+r_code+"?");
  alert.setPositiveButton("YES", new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {
      ff=1;
      alc=false;
    }
  });

  alert.setNegativeButton("NO", new DialogInterface.OnClickListener() {

   @Override
   public void onClick(DialogInterface dialog, int which) {
      // TODO Auto-generated method stub
      ff=0;
   }
  });
  alert.show();
  if (ff==0)
  {
    goto label;
}

I’m new to this android, and help me to avoid this error

Instead of:

label:
...// the rest of your code
if (ff == 0) 
{
    goto label;
}

Use this:

do {
...// the rest of your code
while (ff == 0);

Even better if you can convert it to:

while (ff == 0) {
...// the rest of your code
}
