How do I convert Unix Epoch time to a Java Date object?

Converting Unix Epoch Time to Java Date Object

Unix Epoch time, often referred to as Unix timestamp, represents the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. In Java, we can convert Unix Epoch time to a Date object, which represents a specific moment in time.

To perform this conversion, you can utilize the Date class in Java's java.util package. The Date constructor accepts a long value representing the number of milliseconds since the Epoch.

Example:

Consider the following code snippet:

String date = "1081157732";
Date expiry = new Date(Long.parseLong(date) * 1000);

In this example, we start with a String representing the Unix Epoch time. We then call Long.parseLong() to parse the String and convert it to a long. Since Unix timestamps are typically expressed in seconds, we multiply the resulting long value by 1000 to convert it to milliseconds, the unit used by Java's Date constructor.

By creating a new Date object using the Date(long) constructor and passing the converted milliseconds, we effectively create a Java Date object corresponding to the specified Unix Epoch time. This Date object represents the specific moment in time associated with that timestamp.

Java implementation "write once, run everywhere" is compiled into bytecode and run on a Java virtual machine (JVM). 1) Write Java code and compile it into bytecode. 2) Bytecode runs on any platform with JVM installed. 3) Use Java native interface (JNI) to handle platform-specific functions. Despite challenges such as JVM consistency and the use of platform-specific libraries, WORA greatly improves development efficiency and deployment flexibility.
