I need help coding a program in Java that prints all the strings in an array that contain the same characters in ascending order.

The detailed instructions and examples are shown below:

Problem A021 Write a Class called ProblemA021 to do the following: You must take in an array of strings and print out all combinations of strings that have the same characters as each other. You must print out the combinations in terms of ascending frequency. This is best explained with an example: If the input array is: Input : strArray[] = {"are, abc", "javaforjava", "ear", "bats, era", "forjavajava", "stab", "acres, "definite", "races", "tabs", "bores, robes", "cares", "scare", "brag", "garb, "true", "grab"} Then your program must output: 1: [abc) (definite) (true) 2: [javaforjava, forjavajava) (bores, robes) 3: [are, ear, era) [bats, stab, tabs] [brag, garb, grab] 4: (acres, races, cares, scare) NOTE: The order in each line above does NOT have to be the same as above. Thus, line 2 above can look as follows: 2: [bores, robes] [javaforjava, forjavajava]
