title: Displaying busy status with thread in java
body: <p>I'm writing a Java app which writes to excel sheet bunch of data, and it takes a while to do so. </p>
  
  <p>I'd like to create something like writing out dots to screen like on Linux when you're installing something.</p>
  
  <p>Is that possible in java?printing dots, while other thread actually does the writing to excel, then after its finished the one displaying dots also quits?</p>
  
  <p>I'd like to print dots to console.</p>
