Here is the sample code.


<apex:page controller="LowerCase_to_UpperCase_Controller">
<apex:form >
Value <apex:inputText value="{!value}"/><br/>
lower<apex:outputText id="id1" value="{!lower}" /><br/>
upper<apex:outputText id="id2" value="{!upper}" /><br/>

<apex:commandButton action="{!change}" value="Change" reRender="id1,id2"/>


public with sharing class LowerCase_to_UpperCase_Controller{
    public String value { get; set; }
    public String upper { get; set; }
    public String lower { get; set; }  

    public PageReference change() {
    upper = value.toUpperCase();
    lower = value.toLowerCase();
    return null;

Mark this as best answer if its helps.

You can actually use {!LOWER( stringvariable )} or {!UPPER( stringvariable )},
