What are some examples of type conversion in Java?

What are some examples of type conversion in Java?

In Java, type conversion can be either implicit or explicit. For example, converting an int to a double is implicit: int num = 5; double dNum = num;. Explicit conversion can be done using casting, like double dNum = 5.5; int num = (int) dNum;.

Can you show me more examples of explicit type conversion?

Sure! Here's another example: converting a float to an int. You can do it like this: float fNum = 9.78f; int num = (int) fNum; This will truncate the decimal part.

What about converting a String to an int?

To convert a String to an int, you can use Integer.parseInt(). For example: String str = "123"; int num = Integer.parseInt(str); This will convert the String "123" to the integer 123.

Are there any risks with type conversion?

Yes, there are risks such as data loss during explicit conversion, like converting a double to an int, which truncates the decimal. Always ensure the conversion is safe.
