setting bounds for a constraint in CPLEX Concert Technology Java

I am defining a constraint in a class and later I am calling that class. Now I want to define range for the constraint created. How to set upper bound for the constraint. Relevant part of the code only I have given below.

import ilog.concert.IloConstraint;
import ilog.concert.IloException;
import ilog.concert.IloIntVar;
import ilog.concert.IloLinearNumExpr;
import ilog.concert.IloNumVar;
import ilog.cplex.IloCplex;

import java.util.List;

public class ***** {

    public void model(IloCplex cplex, IloIntVar[] cccDecisionVariable, *****, int *****, List<*****> *****) throws IloException {
        IloLinearNumExpr constraintExpression = cplex.linearNumExpr();   
        constraintExpression.addTerm(cccc.getBbbb(),cccDecisionVariable[ccc.getCccId()];          

        IloConstraint constraint = cplex.addGe(constraintExpression,cccc.getAvailable());
        constraint.setName("gggg");             
    }

}

You might want to use IloRange instead of IloConstraint 

IloRange constraint = cplex.addGe(constraintExpression,cccc.getAvailable());
constraint.setUB(12.5);
