Under the leading position of IE, all kinds of domestic and foreign browser software have appeared like mushroom growth breeding lives. The homepage browsers development and the application have become a computer domain big hot spot in recent years. This article revolves Browsers programming and development, narrated some technologies and authors attainments of carrying the browser in JDK5.0 development, explained browser procedure—MiniBrower which emphatically in the achievement of graduation project. This article uses software engineerings performance procedure, elaborated Browsers analysis, design and code achievement, finally achieved the Browser which has simultaneously glances over many homepages. It can inquire the history to glance over the record, realize opens and preserves the homepage, the ultra connection monitors and responds, with to illegal website filtration and so on. This article take actual operations browser—MiniBrowser as the main axle，introduced browsers design idea and method, simultaneously narrated how each module does coordinate the operation mutually in the browser, completes one to present the homepage the work.
