Why do some experienced programmers write comparisons with the value before the variable? [duplicate]

Answer 1

As a java developer I tend to write expressions like this:

   //primitive check
   if(constant == variable)

   //Object check
   if(constant.equals(variable))

This is particularly important for the object because the expression doesn't error if the variable is null. If the expression were in the other order, a null variable would error. I maintain consistency and do the same order for primitives.
