# LiveData-CombineUtil-Java
LiveData-CombineUtil-Java contains helper functions for LiveData, to combine their latest emissions.
``` java
import static com.zhuinden.livedatacombineutiljava.LiveDataCombineUtil.*;
combine(liveData1, liveData2, liveData3, (t1, t2, t3) -> {
// map to something
}).observe(viewLifecycleOwner, (mapped) -> {
// do something with mapped values
});
```
## Why?
It's useful when you want to combine multiple reactive streams together and get a combined object of the latest values.
## Using LiveData-CombineUtil-Java
In order to use LiveData-CombineUtil-Java, you need to add `jitpack` to your project root `build.gradle.kts`
(or `build.gradle`):
``` kotlin
// build.gradle.kts
allprojects {
repositories {
// ...
maven { setUrl("https://jitpack.io") }
}
// ...
}
```
or
``` groovy
// build.gradle
allprojects {
repositories {
// ...
maven { url "https://jitpack.io" }
}
// ...
}
```
In newer projects, you need to also update the `settings.gradle` file's `dependencyResolutionManagement` block:
```
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven { url 'https://jitpack.io' } // <--
jcenter() // Warning: this repository is going to shut down soon
}
}
```
and then, add the dependency to your module's `build.gradle.kts` (or `build.gradle`):
``` kotlin
// build.gradle.kts
implementation("com.github.Zhuinden:livedata-combineutil-java:1.0.0")
```
or
``` groovy
// build.gradle
implementation 'com.github.Zhuinden:livedata-combineutil-java:1.0.0'
```
