To know about transient , first we need to know about serialization concept .serialization makes an object's state persistent . It means that the object is converted into stream and store in a file . For any object which has to be transmitted over network needs to be converted into bytes .when you specify transient you don't want the variable to be serialized .usually variables are marked as transient when they can be calculated from other variables .e.g . Say we know length and breadth of rectangle , then we can mark area of rectangle as transient since area is calculated from other variables.hope this helps! read less

transient variables are never serialized in java. It marks a member variable not to be serialized when it is persisted to streams of bytes. When an object is transferred through the network, the object needs to be 'serialized'. Serialization converts the object state to serial bytes. Those bytes are sent over the network and the object is recreated from those bytes. Member variables marked by the java transient keyword are not transferred, they are lost intentionally. please have a look at what serialization is.? and also refer this read less

Any fields marked as 'transient' are simply ignored in the serialization process. This is equivalent in...

So when a de serialization is done the variable will not retain its old value but instead will take its...

Transient variables are useful :- when you want to transfer object on a network and don't want any particular variable of that object to be part of that transfer.
