Java 数组问题待解决

请问怎么用简洁的方式把定义好的八个JButton添加到数组里？

JButton[] functionBn=new JButton[8];
JButton addBn,subBn,mulBn,divBn,decBn,equBn,delBn,clrBn;

 JButton[] functionBn = {
                new JButton("addBn"),
                new JButton("subBn"),
                new JButton("mulBn"),
                new JButton("divBn"),
                new JButton("decBn"),
                new JButton("equBn"),
                new JButton("delBn"),
                new JButton("clrBn")
        };

要么声明的时候创建

String[] strings = new String[]{"2","3"};

要么遍历赋值进去。
