`RuntimeException` is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.
`RuntimeException` and its subclasses are *unchecked exceptions* . Unchecked exceptions do *not* need to be declared in a method or constructor's `throws` clause if they can be thrown by the execution of the method or constructor and propagate outside the method or constructor boundary.
## Summary

## Public constructors
### RuntimeException
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
RuntimeException()
```
Constructs a new runtime exception with `null` as its detail message. The cause is not initialized, and may subsequently be initialized by a call to `https://developer.android.com/reference/kotlin/java/lang/Throwable#initCause(kotlin.Throwable)`.
### RuntimeException
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
RuntimeException(message: String!)
```
Constructs a new runtime exception with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to `https://developer.android.com/reference/kotlin/java/lang/Throwable#initCause(kotlin.Throwable)`.
| Parameters ||
|---|---|
| `message` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!: the detail message. The detail message is saved for later retrieval by the `https://developer.android.com/reference/kotlin/java/lang/Throwable#getMessage()` method. |
### RuntimeException
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
RuntimeException(
message: String!,
cause: Throwable!)
```
Constructs a new runtime exception with the specified detail message and cause.
Note that the detail message associated with `cause` is *not* automatically incorporated in this runtime exception's detail message.
| Parameters ||
|---|---|
| `message` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!: the detail message (which is saved for later retrieval by the `https://developer.android.com/reference/kotlin/java/lang/Throwable#getMessage()` method). |
| `cause` | [Throwable](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-throwable/index.html)!: the cause (which is saved for later retrieval by the `https://developer.android.com/reference/kotlin/java/lang/Throwable#getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) |
### RuntimeException
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
RuntimeException(cause: Throwable!)
```
Constructs a new runtime exception with the specified cause and a detail message of `(cause==null ? null : cause.toString())` (which typically contains the class and detail message of `cause`). This constructor is useful for runtime exceptions that are little more than wrappers for other throwables.
| Parameters ||
|---|---|
| `cause` | [Throwable](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-throwable/index.html)!: the cause (which is saved for later retrieval by the `https://developer.android.com/reference/kotlin/java/lang/Throwable#getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) |
## Protected constructors
### RuntimeException
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
protected RuntimeException(
message: String!,
cause: Throwable!,
enableSuppression: Boolean,
writableStackTrace: Boolean)
```
Constructs a new runtime exception with the specified detail message, cause, suppression enabled or disabled, and writable stack trace enabled or disabled.
| Parameters ||
|---|---|
| `message` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!: the detail message. |
| `cause` | [Throwable](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-throwable/index.html)!: the cause. (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) |
