Assume that word is a variable of type string that has been assigned a value. assume furthermore that this value always contains the letters "dr" followed by at least two other letters. for example: "undramatic", "dreck", "android", "no-drip". assume that there is another variable declared, drword, also of type string. write the statements needed so that the 4-character substring word of the value of word starting with "dr" is assigned to drword. so, if the value of word were "george slew the dragon" your code would assign the value "drag" to drword. submit

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.
