java - Dynamic if statement evaluation problem with string comparison -

I have given the example that if i but it is not working properly, use the "age" variable as an integer Instead, I've used the string in the example below. I am "unsuccessful" as the answer to "success".

Can anyone help me?

You must choose or So compare the numerical comparison or string. For this, it is necessary to use the relevant situation and type of age.

Numeric:

  int age = 30; String cad = "age == 30";  

string:

  string ages = "30"; String CAD = "Age. Angle (\" 30 \ ")";
