ICSE − Q & A

What is meant by composite data type and reference data type??

guyz any commercial application ???

static char i;
    static void sum()
    {
        System.out.print(i);
    }
We all knew the default value of char as our text said it should be null or \u0000 ....but when i declared it it aint giving me any output.....Terminal window is absolutely blank...Just check it out plz..........when char is getting replaced with short or double or int then there is valid output..........If char is getting replaced with string then ans is null

Can some1 pl. explain continue using an example

System.out.print((false)?'a':66); // how is it printing B and not 66? can anybody explain...

If anyone gets  a different n twisted prpgram plz share..
