+ * A Java expression.
+ *
+ * <p>
+ * Unlike most of CodeModel, JExpressions are built bottom-up (
+ * meaning you start from leaves and then gradually build compliated expressions
+ * by combining them.)
+ *
+ * <p>
+ * {@link JExpression} defines a series of composer methods,
+ * which returns a complicated expression (by often taking other {@link JExpression}s
+ * as parameters.
+ * For example, you can build "5+2" by
+ * <tt>JExpr.lit(5).add(JExpr.lit(2))</tt>
