Good practice in using properties and local variables
<p>Is it a good practice to use properties as local variable.  In cases where there are many methods which uses some variables, In each method the variable value changes.  This avoids many times creating new variables and the code increases.  Any suggestion?</p>

<pre><code>private void method1(){
     int totalLength = length1 + 10;
     int totalBreath = (breath1 + breath2) + 20;
     int size =  (totalLength * totalLength);
     System.out.println(size);
}


private void method2(){
     int totalLength = length1 + 20;
     int totalBreath = (breath1 + breath2) + 30;
     int size =  (totalLength * totalLength);
     System.out.println(size);
}


private void method3(){
     int totalLength = length1 + 60;
     int totalBreath = (breath1 + breath2) + 10;
     int size =  (totalLength * totalLength);
     System.out.println(size);
}
</code></pre>

<p>As you can see, totalLength, totalBreath, size is repeated in every method.  Can i make them as fields of the class?  So, i need not declare it in every method.</p>

<pre><code> private void method1(){
     totalLength = length1 + 10;
     totalBreath = (breath1 + breath2) + 20;
     size =  (totalLength * totalLength);
     System.out.println(size);
}
</code></pre>
