    Default Re: decimal and hexdecimal

    you'll have to be more specific than that. Do you mean inside your Java source code? It will automatically be considered to be in decimal form if it looks like a number

    123 // valid decimal number
    154 // valid decimal number
    1a5 // invalid decimal number, compile error

    You must explicitly tell Java that a number is hexadecimal by putting an "0x" (that's a zero followed by a lower-case x).

    0x5d // valid hexadecimal number
    0x4efd // valid hexadecimal number
    0x100 // valid hexadecimal number

    If you're not really curious about know what type it is but you just want it converted into an integer you can do this.

    Integer.decode("0x4efd")

    // Json

    Question Re: decimal and hexdecimal

    thanks

    and i have one more doubt

    if a is an integer variable, i can assign it as 0x5a5a5a it will print the decimal on console.
    and b is an integer variable , i can assign it 90. it will also print 90 on console.

    in that a is assigned by hex decimal so i want to divide hex decimal like 5a,5a ,5a
    and it will display on console 90,90,90

    is it possible
