solve question 2, Java

1. A method named isANumber that takes a character and returns true if the character is a number (1-9) and false otherwise. 2. A method named isAnOperation that takes a character and returns true if the character is one of the operations +, -, *, /, %, and false otherwise. 3. A method named getResult that takes three characters: the first two must contain numbers (1-9), the third must contain one of the five operations: +, -, *, /, %. The method returns a String that includes the two numbers, the operation, and the result. It must make sure that the first two characters are numbers by invoking the isANumber method, and that the third character is one of the valid operations by invoking the isAnOperation method. If not, it must return the statement “Invalid Input!". For example, if the first two characters contain the numbers '3' and 4', and the operation + is passed to the method it must return the following String: 3+4=7 4. In your main method, define a character named operation and initialize it with one of the characters: +, -, *, /, %. Iterate over the characters from 1' to '9', print out the result of performing the operation defined in operation for each one of them with the characters from '1' to '9', each on a separate line. Test your code by changing the operation variable for the five possible operations. Note: use the printf method with %s to make your output aligned, such that each arithmetic statement takes 8 fields. Your output must look something like this (example if operation is +). 1+1=2 1+2=3 1+3=4 1+4=5 1+5=6 .... ..... 2+1=3 2+2=4 _2+3=5 2+4=6 2+5=7 9+1=10 9+2=11 9+3=12 9+4=13 9+5=14 ..... ...
