This soul began to dwell in this body named Ganesh Patekar since 31/07/1987 in Solapur, Maharashtra, India.
Being youngest child in the family had happy childhood but I was also an obstinate kid As days go by I became more amiable.
I had persuaded Bachelors of computer application( BCA, Batch 2007-10 ) from Sinhgad College of Science, Pune. I’m so greedy about learning so couldn’t stop there so persuaded Master of computer application ( MCA ) from Sinhgad Institute of Management, Pune. I used to act as emcee and compare in college events. Those were the best days of life.
I really adore to learn new things. I always eager to write a beautiful code I enjoy visiting natural places near by Pune on weekends.
I’m passionate about maintaining good physic so I do yoga, pranayama and workout regularly because I think, health is wealth.
Pune, Maharashtra, India.

By the way this question is from Assessment Test Q.14, OCA Java SE 8 Programmer I Exam Guide by Jeanne Boyarsky and Scott Selikoff, Sybex. I edited the title accordingly to prevent confusion for future references.

Sorry, StringBuilder would be good than String since String is immutable.

I guess you mean to say, how to compare two numbers to find out same digits present in those two numbers. For example num1 = 1028 and num2 = 2205 Output: 0 2

In that case first you need to separate each digits of num1 to compare with every digits of num2. I think you better use String rather than int type for numbers since number such as 0235 will create problem while separating digits using % and / operators.

See String for charAt(..) and other String methods which might help.

One of the rules of method overriding is: The access modifier of an overriding method must provide at least as much access as the overridden method ( default method of interface ).

Implicitly the access modifier of default method is public but in MultiInt class overriding method int doStuff() has package-private access modifier which is weaker or lesser accessible than public hence the compilation error.

Why do you think you need to String variables? You don't need two String variables, only one is enough.

I think you don't need to declare String variables as static unless there is a valid reason it be static, either declare it as an instance ( non-static ) variable may be with private modifier? then you can initialize it using constructor or you can declare and initialise String variable as local variable in main method.
