Regarding SCJP 1.4

[Srikanth Iyer]

During the exams scjp 1.4 is there is a quesiton on bitwise oprators or the shift operators will the binary value of the numbers be given???

Hi Srikanth ,

There will be quite a few questions on Bitwise & shift operators. The binary value wont be given . We have to convert the decimal value to the binary value and then work on them .

eg : 3<<2 ;
3*2^2;
3*4;
3<<<2 ;

Which two of the above are same ?

Hope I answered your question .

Thank you rakesh

Also, the numbers you need to convert to binary will not be that difficult. For example, you might see values in the neighborhood of 12 or 15 (just enough to test your knowledge of binary conversion) -- but you should not need to convert something like 6763 (which is 1101001101011, by the way).

Note: Negative one is commonly used in these problems, so you definitely need to know that -1 is all 1's in binary.
