Problem - Java Programming (Source code located below, just fill in the missing code in the designated areas) :)

Please provide a screenshot once complete of it compiled which should look sorta similar to the Sample one provided.

Develop a Java application named Problem1.java that uses a simple GUI laid-out inside the application main window (lets call it GUI). The main window should be sized to be 75% of your platforms screen and must contain the following five widgets. Hint See the Sample Program GUI for a sample version of the GUI.

-a 1-row, full-window-width, red-text Label "Enter "important" quote below"

-a multi-row, full-window-width text area (lets call it textArea)

-2 command buttons (labeled "Show" and "Exit")

-a panel to draw on (lets call it drawingPanel) that occupies most of the window

As your application runs, it must respond to GUI events as follows

-A left-click on the "Show" command button must process the string text entered by the program user into textArea. Note If you like, you may provide a favorite quotation as a default value for text that is different from the one Dr. Hanna used.

-A left-click on the "Exit" command button must cause the application to terminate normally.

To process text, you must

-Tokenize text into a collection of n strings (lets call it words[i], i [ 0,n-1 ]). You may assume (1) that text is always composed of 3 or more words arranged as 1 or more sentences; and (2) that the words in text aredelimited (that is, separated from each other) by any combination of one or more slashes '\\', double-quotes '\"', tabs '\t', spaces ' ', end?of?lines ' ', periods '.', commas ',', colons ':', semicolons ';', dashes '-', question marks '?', and/or exclamation points '!'. Note You may use the String class method split(), but you can also use the StringTokenizer class instead of the String split() method.

-Sort the n strings in words[] into descending lexicographic order.

-Assume panelD is the smaller of the two dimensions of drawingPanel. Draw a red, un-filled outer circle with radius_outer = 0.40*panelD pixels and center (xc,yc) = (panelD/2,panelD/2).

-Draw another concentric red, un-filled inner circle with a much smaller radius_inner = 0.05*panelD pixels (concentric means the inner circle has the same center as the outer circle, namely,(xc,yc)).

-Let a = 2p radians. For i [ 0,n-1 ], let angle[i] = (p/2-a*i), draw the radial[i] blue line-segment at angle[i] so that it extends from the inner circle to a point that is 0.05*panelD pixels beyond the outer circle. Every radial[i] line-segment must be tipped with a radius = 5-pixel, red, filled circle. Notes (1) radial[0] points straight up, angle[0] = p/2 radians; and (2) every radial[i] line-segment, if extended, would intersect with the shared center of the two red, un-filled circles.

-Draw a green, un-filled, n-sided, regular polygon circumscribed by the outer circle such that the polygon line-segments connect the points where the radial[i] blue line-segments intersect the outer circle.

-Draw the words[i] 1 character at a time along radial[i], i = 0,1,..., n-1, using (1) font family = "Courier New" and font size = 24; (2) a font color cyclically selected from the set of Color constants { black,red,green,blue,cyan,yellow,magenta }; and (3) a font style cyclically selected from the set of constants { PLAIN, ITALIC, PLAIN+BOLD, ITALIC+BOLD }. For example, all the characters in words[0] must be displayed as PLAIN black text, words[1] as ITALIC red, words[2] as PLAIN+BOLD green,...,words[6] as PLAIN+BOLD magenta, et cetera. Draw all characters in all words[i]so that the lower-left hand corner of each character rests close to its radial line-segment and with the first character of each words[i] placed close to the inner circle.
