Question

Please use Java code and Strings, the String class (format), arrays, Math.random() and Scanner objects to answer, do not use random class and arrayLists class, thank you

(3) Image Program o0000.o.O Write a program called ImageProgram that creates a 10 x 10 two-dimensional array of 100 ooo..o00.o randomly-generated booleans. The program .0o.o0o..O should then display an image that is represented 0o.000.O by the array showing (as a grid of O' or. characters), where O is shown when the boolean 000. .0oo is true and ..' is shown otherwise. See here Then, your program should determine and print | .oooo..o. the longest horizontal sequence of O characters .0.000. as well as the longest vertical sequence of O characters by examining the two-dimensional . .O.0o..o array. Here is some sample output (although The longest horizontal sequence is 5 results will vary each time that you run it. and the highlighting was only added for emphasis): The longest vertical sequence is 8
