i ger 2 errors:
error: cannot find symbol
Integer age = new Integer(); age.parseInt(Keyboard.readint() );
and the arrow is under . in Keyboard.readint

no suitable constructor found for Integer()
Integer age = new Integer(); age.parseInt(Keyboard.readint() );
the arrow is under new

[NormR1]

Does the Keyboard class have a static method: readint()?

Integer age = new Integer(); age.parseInt(Keyboard.readint() );

Is this a typo? There is a ; in the middle of the statement.

Don't put two statements on the same line.
The parseInt method is static, you do not need an instance of the class to use it:
... Integer.parseInt(....

Use the classname just like you are using Keyboard

[DJSAN10]

Integer age = new Integer(); age.parseInt(Keyboard.readint() );

What NormR1 just suggested , that and i think readInt() might be the correct one. I don't know check the syntax
