Insert Pi chart In JSP Page

Use Google Pi Chart API

Step 1

Add lib
<script type="text/javascript" src="https://www.google.com/jsapi"></script>

Step 2

google.setOnLoadCallback(drawChart);

Step 3

Write Script Function

function pichart(admin_pending,late,regular,admin_verify)

/* function pichart() */

{

// Create the data table.

var data = new google.visualization.DataTable();

data.addColumn('string', 'Topping');

data.addColumn('number', 'Slices');

data.addRows([

['Admin Pending', admin_pending],

['Late', late],

['Regular', regular],

['Admin Verify', admin_verify]

]);

 

// Create the data table.

// Set chart options

var options = {'title':'Analysis Report',

'width':500,

'height':200,

};

// Instantiate and draw our chart, passing in some options.

var chart = new google.visualization.PieChart(document.getElementById('pichart_div'))

chart.draw(data, options);

     }

Program for String Operations

Interviewer check your Programming Logic.
like Statement

String s="I am Bharat@123 from shirur";

find the integer in the string and addition them. for example 1,2,3 integer value and addition 1+2+3=6
find the latter in given String.for example "r" in the 2 string "Bharat" and "Shirur" then count is=2

Program

String s="I am Bharat@123 from shirur";
char[] a=s.toCharArray();
int count=0,addition=0;
for(int i=0;i<a.length-1;i++)
{
if(Character.isDigit(a[i]))
{
int myInt = a[i] - '0';
addition=addition+ myInt;
System.out.println(addition+"number=="+a[i]);
}
}
String[] splits = s.split(" ");
for(int k=0;k<splits.length;k++)
{
System.out.println(splits[k]);
if(splits[k].indexOf("r") != -1)
{
count=count+1;
}
}
System.out.println("count=="+count);
System.out.println("addition=="+addition);

Out Put

I

am
Bharat@123
from
shirur
count==2
addition==6
