i am very new to JBuilder,

but can someone answer the following question.

I have created a class which has an age attribute as an iont

i.e. int age;

I trying to ask the user to input their age and then setting it to
Object.age

However, i am using a textField comp[onent, but it won't let me set the
value of age 
because it is reading it as a string and not an integer, 

can anyone tell me which component allows me to read in integers and set
the values?
