# Update Data in Cache

Existing data from the cache can be updated through `updateCacheValue()` method.It comes with the following two
variants,

### Update cache value of a key

This variant updates the value of the existing key, by passing the updated value as parameter to the
`updateCacheValue()` method.

The expiry time of the key is maintained as its previous value.

#### Sample Code Snippet 

**Package Imports**

```java
import com.zc.component.cache.ZCCache; 
import com.zc.component.cache.ZCSegment;

```

```java
//Get a Cache Instance 
ZCCache cacheobj=ZCCache.getInstance(); 
//Get an instance of a specific segment with a segment ID 
ZCSegment segment = cacheobj.getSegment(1510000000054091L);  //replace segment id
// Updates the value of the existing cache’s key 
ZCCache.getInstance().updateCacheValue("time_taken", "10");

```

### Update cache value with expiry time

Similar to the above one, this variant updates the value of the key, where the expiry time of the key is also passed as
the parameter to the method.

The value of the expiry time is updated with the new value passed as a long int value in hours.

#### Sample Code Snippet 

**Package Imports**

```java
import com.zc.component.cache.ZCCache; 
import com.zc.component.cache.ZCSegment;

```

```java
//Get a Cache Instance 
ZCCache cacheobj=ZCCache.getInstance(); 
//Get an instance of a specific segment with a segment ID 
ZCSegment segment = cacheobj.getSegment(151xxxxxxxxxL); 
//Update the value of the existing cache’s key with its expiry time 
ZCCache.getInstance().updateCacheValue("time_taken", "48", 2L);

```
