本文實例講述了Java中Json解析的方法。分享給大家供大家參考，具體如下：
首先準備一個JSON格式的字符串

* String JsonStr = "{object:{persons:" +"[{name:'呵呵',image:'http://10.0.159.132:8080/Web/s1.png'}," +"{name:'哈哈',image:'http://10.0.159.132:8080/Web/s1.png'}," +"{name:'嘿嘿',image:'http://10.0.159.132:8080/Web/s2.jpg'}]}}";* 然后定義一個Person類**class Person{ private String name,image; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getImage() { return image; } public void setImage(String image) { this.image = image; }} |

希望本文所述對大家java程序設計有所幫助。
