Accept a Input from end user.

Hi, 

Can someone give me a little guidance here to understand how taking a input from user works here is Salesforce.

I was going through Apex developer's guide and I'vea almost read half of the book, but still didn't see any example to take a input from user. Like in Java we can use a DataInput stream or scanner class to take a input from user, but I've not seen anything like in Apex.

Can someone point me to the documentation which can help me to understand how apex lets your customer to input the data in Salesforce.

Any help will be highly appreciated.

Thanks

Hello Sohan,

In apex there are no need DataInput stream or scanner class to take a input like JAVA. You need only create a variable  in controller & connect with apex inputText value in VF Page.

You can debug value in save method 
public class MyController{
    public string var1{get; set;}
    public MyController() {
        
    }
	public void save(){
	    system.debug(var1);
	}
}
<apex:page controller="MyController">
    <apex:pageMessages id="pgId"></apex:pageMessages>
    <apex:form id="frmId">
        <apex:inputText value="{!var1}"/>
        <apex:commandButton value="Save" action="{!save}" reRender="pgId, frmId"/>
    </apex:form>
</apex:page>

Hello,

Salesfore platform allows 3 different types of methods below to link VF page to a custom controller happens 

Setter - Passes the user-specified values from a VF page to a controller
Getter - Returns the values from a controlle
Action - Performs logic

Getter & Action - Will be prompted when you create a new VF page
Setter - You need to create manually
