The problem you are having is that neither "foo" or "bar" are able to be
parsed as an integer, or put in another way "foo" and "bar" cannot be
represented as an integer.  The Intger.valueOf(String) method is only
valid if the Sting is a String representation of an integer.  Try this;

String a = "yes";
String b = "ls";
String aaString = "25";
String bbString = "937";
try {
    int aa = Integer.valueOf(aaString).intValue();
    int bb = Integer.valueOf(bbString).intValue();
}
catch (numberFormatException e) {
    System.out.printLn(e.getLocalizedMessage());
}
System.out.println(aa);
System.out.println(bb);
