Here is an example of a Java program that takes a character, an integer width and an integer height as input and prints a rectangle of that character with the given width and height:

In this program, the user is prompted to enter a character, an integer width and an integer height using the Scanner class. The input is then stored in the variables "c", "width" and "height" respectively.
Two nested for loops are used to print out the rectangle of the given character, the outer loop runs for the number of times of the given height and the inner loop runs for the number of times of the given width. Each time the inner loop runs, the character is printed, and after the inner loop runs for the width times, the program moves to the next line with the help of the System.out.println()
Please keep in mind that this is just one example of a program to print a rectangle of a given character, width and height and there are many other ways to write this program depending on the requirements.
