Creating Json array using java array

[Ambislm]

This is my sample application which provides result as follows:

Array Values  : 
arr[0][0] :6
arr[0][1] :0 
arr[0][2] :0 
arr[1][0] :0 
arr[1][1] :0    
arr[1][2] :0

am using the jQuery Highcharts:

chart = new Highcharts.Chart({
                              chart: {
                                renderTo: 'container',
                                defaultSeriesType: 'column'
                              },
                              title: {
                        text: document.chart.chartTitle.value
                              },                                            
                              series: [{
                                 name: 'USA',
                                 data: [50, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
                               }, {
                                 name: 'New York',
                                 data: [83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0, 104.3, 91.2, 83.5, 106.6, 92.3]
                               }, {
                                 name: 'London',
                                 data: [48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2]
                               }, {
                                 name: 'Berlin',
                                 data: [42.4, 33.2, 34.5, 39.7, 52.6, 75.5, 57.4, 60.4, 47.6, 39.1, 46.8, 51.1]
                              }]
                       });

I have to pass values in series such as:

name:'vehicle reporting'
data: [6,0,0 ]

name:'bill_count'
data: [0,0,0 ]

from that array[][] values. how can i convert those result into json format and pass it to jquery chart value?

can anyone provide me with any example.
Thanks in advance.
