Defining as constants in Java

lis开发者_StackOverflow社区t.loadRequestParms(request, 'a', 20);

This method takes three parameters

1. a request object.
2. a char
3. an integer

Now how to define these as constants somewhere and use it in this method.

I think I understand what you mean, but more detail would have been useful.

static final Request MY_REQUEST_CONST = someRequest;
static final char MY_A_CONST = 'a';
static final int MY_INT_CONST = 20;

list.loadRequestParms(MY_REQUEST_CONST, MY_A_CONST, MY_INT_CONST);

Some things to note. A constant in Java is created by the final static keywords. Convention suggests that constant variable names are uppercase.

Constants? You mean variables that don't change and are final? Same copy of which lasts all throughout, i.e. are static? And they can also be publicly accessible.
