java.util.Date to java.sql.Date

Bipartite Graph

In this example, we shall show you how to convert a java.util.Date object to a java.sql.Date object. This conversion is usually necessary when a Date object needs to be written in a database. java.util.Date represents a specific instant in time, with millisecond precision. It represents both date and time. java.sql.Date is a wrapper around millisecond value and is used by ...

Java Get current date and time

Bipartite Graph

There are a couple of ways to get the current time and date in Java. You may get the number of milliseconds since January 1, 1970, 00:00:00 GMT using System.currentTimeMillis() and calculate the time by yourself (a problem given to beginners, but too much work if you are developing something), you may use a library not included in the JDK ...

java.util.Date Example – How to use Java util date

Bipartite Graph

In this example we will show how to use the Java util Date class java.util.date . Class Date represents a specific instant in time, with millisecond precision. 1. Date constructors The java.util.Date class supports two constructors: Date() This constructor initializes a Date object with the current date and time. Time is measured to the nearest millisecond. Date(long millisec) This constructor ...

Get Date

Bipartite Graph

With this example we are going to demonstrate how to get a Date in Java. The class Date represents a specific instant in time, with millisecond precision. In short, to get a Date object you should: Create a new Date object, using the Date() constructor. The constructor allocates a Date object and initializes it so that it represents the time ...

Date from specific time

Bipartite Graph

This is an example of how to get a Date from a specific time. The class Date represents a specific instant in time, with millisecond precision. Getting a Date from a specific long time implies that you should: Create a new Date object, using the Date(long date) constructor, with a long parameter. The constructor allocates a Date object and initializes ...

Convert Date to millisec

Bipartite Graph

In this example we shall show you how to convert a Date to millisec, that means get the long number of millisec that represent a Date object. A Date object represents a specific instant in time, with millisecond precision. To convert a Date to millisec one should perform the following steps: Create a new Date object, using the Date() constructor, ...

Compare Date objects with compareTo method

Bipartite Graph

With this example we are going to demonstrate how to compare Date objects with compareTo method of the Date class. In short, to compare a Date object with another you should: Create a new Date object, using the Date() constructor, that allocates a Date object and initializes it so that it represents the time at which it was allocated, measured ...

Compare Date objects with before method

Bipartite Graph

This is an example of how to compare Date objects with before(Date when) API method of Date. Comparing a Date with another Date using before(Date when) method implies that you should: Create a new Date object, using the Date() constructor, that allocates a Date object and initializes it so that it represents the time at which it was allocated, measured ...

Compare Date objects with after method

Bipartite Graph

In this example we shall show you how to compare Date objects with after(Date when) method of Date, that tests if a Date is after the specified one. To compare a Date object with another Date object, using after(Date when) API method of Date one should perform the following steps: Use the simple Date() constructor, to allocate a Date object ...
