EX1: investigate the graphic programs listed above
EX 2) Investigate mouseF4.java mouseP4.java and draw the following shape by using the program
sliderTest.java
EX3 ) OvalP.java and SliderTest.java is given above. Investigate these programs. By using starP.java
ctreate SliderTest1.java to draw a 5 sided star and change the size of the star through changing the
slider position.
EX4 ) Investigate shapeP and listA1.java. ChangelistA1.java to a new program listA2.java so that
page will be divided into two pages by using a JTabbedPane layout formatting. In the first page list
controls will be located. In the second page the shape will be located

Investigate these programs. The following program is given to draw multi-sided shapes (triangle,
rectangle, pentagon, hexagon etc.). By changing star.java to create multiangle.java create a program to
draw multisided shaped instead of stars in the star.java program.
