Why doesn't the calculator work? [closed]

Tried to write a calculator. Level of knowledge 0.

When I press any of the actions, everything is fine: the field is cleared - you can write chislo2. When I click the same, whatever the action, it gives 1 and that's it. Tell me, what's the problem?

PS eclipse itself does not see errors
