int total_Val=application.getAttribute("xyz");
//code to convert object into integer

Please help me to understand this conversion process if you can.

Hello,

I don't have very much knowedge, but have tried this type of conversion.
I suggest you to try below code for the conversion object into integer:


application.setAttribute("xyz",new Integer(5));

int total_Val=(Integer)application.getAttribute("xyz");


If you execute this code you will get the object in the integer type.

I hope this clears your doubts.

To convert object into integer, you should follow the below steps:

1. first you have to create the object
2. then convert object into string
3. and finally convert string into integer or float

Code:

int p =Integer.parseInt( object.toString() );

Please use below inbuild methods of java to convert object into integer or long or float:

1. toInt(java.lang.String pqr)
// Converts the String object pqr to an int type.

2. toLong(java.lang.String pqr)
//Converts the String object pqr to a long type.

3. toFloat(java.lang.String pqr)
Converts the String object pqr to a float type.
