Hi Nagendra,

Greeting to you!

I have written a component and controller as per your requirement it contains two checkbox if you click one one checkbox it will show selected checkbox value
and disable the other checkbox and vice-versa.

checkbox.cmp -------------
<aura:component >

    <div class="slds-box slds-theme_default">
    <lightning:input aura:id="checkbox1" type="checkbox" label="checkbox 1" name="checkbox 1" onchange="{!c.handleCheckbox1}"/>
    <lightning:input aura:id="checkbox2" type="checkbox" label="checkbox 2" name="checkbox 2" onchange="{!c.handleCheckbox2}"/>


 handleCheckbox1 : function(c, e, h) {
     alert( e.getSource().get(''));

    handleCheckbox2 : function(c, e, h) {
         alert( e.getSource().get(''));
I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.

Thanks and Regards,
Deepali Kulshrestha
