ass Numberopslarks$)$method accepts a String containing numeric inet, and return a corresponding int For exampletheinput is $"123",$ the method returns the int $123.$ssumethe number in the string will always positive.The string can also contain non$-$digit characters on either side of the digit characters. Your method should ignore characters that are not digits, and still return the correct integer. For example:"abc$123$"should return $123"123$ def"should return $123$"abc$123$def" should return $123$Corresponds to test$00$ in MidtermTest. javapublic static int fromString $($String num$)30323334$return $-1$; $//$ modify this$/*(6$ marks$)$accepts an integer as input, and returns$*$ This method$3940*$ an array of ints.
