java - Setting byte field in an object -

-

i have simple program below:

class serializationbox implements serializable {      private byte    serializableprop    = 10;      public byte getserializableprop()     {         return serializableprop;     }      public void setserializableprop(byte serializableprop)     {         serializableprop = serializableprop;     } }  public class serializationsample {      /**      * @param args      */      public static void main(string args[])      {          serializationbox serialb = new serializationbox();         serialb.setserializableprop(1); // here error } }

at indicated place in code error "the method setserializableprop(byte) in type serializationbox not applicable arguments (int)".

i believed per link http://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html , allowed pass -128 127 arguement.

please let me know missing?

you have cast integer byte:

serialb.setserializableprop((byte) 1);

notes:

  • when do

    private byte serializableprop = 10;

  • 10 integer, not binary number. specify number binary have use following syntax:

    private byte serializableprop = 0b10;                                 ^^
