Java 相关的 有集合展示 这个样子没看懂

 var aoCols=[{ aTargets : [ 0 ], mData : "id", sClass : "text-center", sTitle : "<input type='checkBox' class='TableCheckall'>", sWidth : "20px"},
                    { aTargets : [ 1 ], mDataProp : "", sTitle : "序号", bSortable : false, sClass : "text-center",sWidth:30,mRender:function(v){
                        return index++;
                    }},
                    { aTargets : [ 2 ], mDataProp : "issueTitle", sTitle : "事件", bSortable : false},
                    { aTargets : [ 2 ], mDataProp : "issueTypeName", sTitle : "故障类别", bSortable : false},

                    { aTargets : [ 3 ], mDataProp : "assetName", sClass : "text-center", sTitle : "设备", bSortable : false,sWidth:120,mDataProp : function(data){
                        if(data.assetId==null||data.assetId=="0")
                            return "";
                        else
                            return "<a class='nlist' href='javascript:;;;' onclick= maintainReportSvc.fnAssetDetail('"+data.assetId+"','"+data.assetName+"')>"+data.assetName+"</a>";;
                    }},
                    { aTargets : [ 4 ], mDataProp : "applyUserName", sClass : "text-center", sTitle : "发起人", bSortable : false,sWidth:60},

                    { aTargets : [ 5 ], mDataProp : "happenTime", sClass : "text-center", sTitle : "发起时间", bSortable : false,sWidth:120,mRender: function(v){
                        if(v==null)
                            return "";
                        else
                            return v.substring(0,16);
                    }},
                    { aTargets : [ 6 ], mDataProp : "notifyTime", sClass : "text-center", sTitle : "派单时间", bSortable : false,sWidth:120,mRender: function(v){
                        if(v==null)
                            return "";
                        else
                            return v.substring(0,16);
                    }},
                    { aTargets : [ 7 ], mDataProp : "mRequireTime", sClass : "text-center", sTitle : "要求(小时)", bSortable : false,sWidth:120},
                    { aTargets : [ 8 ], mDataProp : "mUserName", sClass : "text-center textoverflow", sTitle : "派单对象", bSortable : false,sWidth:120},
                    { aTargets : [ 9 ], mDataProp : "maintainTime", sClass : "text-center", sTitle : reportType=="1"?"维护时间":"维修时间", bSortable : false,sWidth:120,mRender: function(v){
                        if(v==null)
                            return "";
                        else
                            return v.substring(0,16);
                    }},

这就是一个JavaScript中声明的集合而已。只不过用的是JSON数据格式来显示的。
比如：
声明 数组名 = [{name:value},{name:value}]
var aoCols = [{ aTargets : [ 0 ], mData : "id", sClass : "text-center", sTitle : "", sWidth : "20px"},
{ aTargets : [ 1 ], mDataProp : "", sTitle : "序号", bSortable : false, sClass : "text-center",sWidth:30,mRender:function(v){
return index++;
}}]

这是json数组吧，你上网用JSON在线解析试试

去json.cn试试吧，是个json数组
