Setting Short Value Java

Question

I am writing a little code in J2ME  I have a class with a method setTableId Short tableId   Now when I try to write setTableId 100  it gives compile time error  How can I set the short value without declaring another short variable   When setting Long value I can use setLongValue 100L  and it works  So  what does L mean here and what s the character for Short value    Thanks

There is no such thing as a byte or short literal  You need to cast to short using  short 100

You can use setTableId  short 100    I think this was changed in Java 5 so that numeric literals assigned to byte or short and within range for the target are automatically assumed to be the target type  That latest J2ME JVMs are derived from Java 4 though

Generally you can just cast the variable to become a short   You can also get problems like this that can be confusing  This is because the   operator promotes them to an int    Casting the elements won t help     You need to cast the expression

In Java  integer literals are of type int by default  For some other types  you may suffix the literal with a case-insensitive letter like L  D  F to specify a long  double  or float  respectively  Note it is common practice to use uppercase letters for better readability   The Java Language Specification does not provide the same syntactic sugar for byte or short types  Instead  you may declare it as such using explicit casting   byte foo    byte 0  short bar    short 0    In your setLongValue 100L  method call  you don t have to necessarily include the L suffix because in this case the int literal is automatically widened to a long  This is called widening primitive conversion in the Java Language Specification
