Java AWT | Dimension Class
Dimension class is a part of Java AWT. It contains the height and width of a component in an integer as well as double precision. The use of Dimension class is that many functions of Java AWT and Swing return dimension object.
Constructors of the Dimension class
- Dimension() : It will create a new Object with height and width set to zero.
- Dimension(Dimension d) : It will create a new Object with same height and width as of the specified object.
- Dimension(int w, int h) : It will create a new object with specified height and width.
Methods of Dimension Class
Method | Explanation |
---|---|
equals(Object o) | checks whether the two dimension object are equal or not. |
getHeight() | returns the height of the dimension object |
getWidth() | returns the width of the dimension object |
getSize() | returns the size of dimension object. |
hashCode() | returns the hashcode for dimension. |
setSize(Dimension d) | set size of the object to specified dimension |
setSize(double width, double height) | set the height and width to specified double value |
setSize(int width, int height) | set the height and width to specified integer value |
Below programs illustrate the Dimension Class :
- Program to show the functions of dimension class(Integer precision).
Java
// Java Program to show the functions // of dimension class(Integer precision) import java.awt.*; class dimen { // Main Method public static void main(String args[]) { // create dimension Dimension d = new Dimension(); Dimension d1 = new Dimension( 20 , 30 ); Dimension d2 = new Dimension(d1); // set height and width of dimension d d.setSize( 30 , 30 ); // equating dimensions System.out.println( "Dimension d and d1 " + "are equal = " + d.equals(d1)); System.out.println( "Dimension d and d1 " + "are equal = " + d1.equals(d2)); // print hashcode System.out.println( "Hashcode of Dimension " + "d = " + d.hashCode()); // display dimension display(d, "Dimension d" ); display(d1, "Dimension d1" ); display(d2, "Dimension d2" ); } // display dimension public static void display(Dimension d, String s) { System.out.println(s + " Height = " + d.getHeight() + " Width= " + d.getWidth()); } } |
Output
Dimension d and d1 are equal = false Dimension d and d1 are equal = true Hashcode of Dimension d = 1860 Dimension d Height = 30.0 Width= 30.0 Dimension d1 Height = 30.0 Width= 20.0 Dimension d2 Height = 30.0 Width= 20.0
Output:
Dimension d and d1 are equal = false Dimension d and d1 are equal = true Hashcode of Dimension d = 1860 Dimension d Height = 30.0 Width= 30.0 Dimension d1 Height = 30.0 Width= 20.0 Dimension d2 Height = 30.0 Width= 20.0
- Program to show the functions of dimension class(Double precision).
Java
// Java Program to show the functions // of dimension class(Double precision) import java.awt.*; class dimen { // Main Method public static void main(String args[]) { // create dimension Dimension d = new Dimension(); Dimension d1 = new Dimension( 20 , 30 ); Dimension d2 = new Dimension(d1); // set height and width of dimension d d.setSize( 30.3 , 30.45 ); // equating dimensions System.out.println( "Dimension d and d1" + "are equal = " + d.equals(d1)); System.out.println( "Dimension d and d1" + "are equal = " + d1.equals(d2)); // print hashcode System.out.println( "Hashcode of Dimension d = " + d.hashCode()); // display dimension System.out.println( "See the values are rounded" + "off to ceiling in dimension d" ); display(d, "Dimension d" ); display(d1, "Dimension d1" ); display(d2, "Dimension d2" ); } // display dimension public static void display(Dimension d, String s) { System.out.println(s + " Height = " + d.getHeight() + " Width = " + d.getWidth()); } } |
Output
Dimension d and d1are equal = false Dimension d and d1are equal = true Hashcode of Dimension d = 1984 See the values are roundedoff to ceiling in dimension d Dimension d Height = 31.0 Width = 31.0 Dimension d1 Height = 30.0 Width = 20.0 Dimension d2 Height = 30.0 Width = 20.0
Output:
Dimension d and d1are equal = false Dimension d and d1are equal = true Hashcode of Dimension d = 1984 See the values are roundedoff to ceiling in dimension d Dimension d Height = 31.0 Width = 31.0 Dimension d1 Height = 30.0 Width = 20.0 Dimension d2 Height = 30.0 Width = 20.0
