title: JAVA cannot convert from int to short
body: <p>Hi I am new one here and this is my first question:
  I have a code with simple aritmetic operator.
  But it won't works:</p>
  
  <pre><code>int a = 10;
  short premennaTypuShort = (short)a;     /*retyped variable a into short type and entered into new variable*/
  premennaTypuShort = premennaTypuShort - 7;
  /*now i am trying to decrease the number but eclipse wrote that cannot convert from int to short.*/
  </code></pre>
  
  <p>i am trying to decrease the number specified as short but eclipse wrote that cannot convert from int to short. I don't undertand why.
  so where is the problem ? how can I repair this error?</p>
