Sample Code:
Account acc = new Account(Name = 'Account Name', Phone = '8888888888', Industry = 'Agriculture');
//Code to convert Account to JSON string
String str = JSON.serialize(acc);
system.debug('Account JSON Data - ' + str);
//Code to convert JSON string to Account
Account acc1 = (Account)JSON.deserialize(str, Account.Class);
system.debug('Account Data - ' + acc1);
Output:
Here in below example the default value in picklist is “Apple”.

aura:if evaluates the isTrue expression on the server and instantiates components in either its body or else attribute. Only one branch is created and rendered. Switching condition unrenders and destroys the current branch and generates the other.
In aura:if tag we can not use &&,AND,||,OR operator for multiple conditions in isTrue attribute, but we can use logical functions in aura:if tag like or(), and().
Here is the example how to use multiple Boolean conditions in aura:if tag.
Lightning Component:
<!--Sample.cmp-->
<aura:component implements="flexipage:availableForAllPageTypes,force:appHostable">

<aura:attribute name="attribute1" type="boolean" default="true"/>

<aura:attribute name="attribute4" type="boolean" default="false"/>
