JButton size grater than specified : I had created a `jframe` and simply added a `jbutton` to it and  had set the size of the `jframe` as 500,500 and size of the `jbutton`
as 40,60 but when I executed my program, my `jbutton` was covering the whole of my `jframe`. I
tried many things and looked into many sources but i could not find a solution. Please help me solve this.
