Complete all parts of the following problem (in a single java class):
1) create a main() method with a switch statement that calls either a sum() or factorial() method, depending on what selection the user of the program makes - ask the user to enter a selection (with system. out. create a scanner then read the user's input with a call to scanner then call the appropriate method in a switch (the string that was read from the call to scanner. next() should be what you use as your switch condition).
2) create a method, to include a for loop that will :
get a scanner and input a number from the keyboard in the method will take one parameter and calculate the sum up to that number. for example, if you pass 5, it it will calculate 1+2+3+4+5 and will return it back to main() method.
3) create another method, and repeat what was done for the sum() method above but compute the product instead.
