Don't need a whole program or anything just the method line describing this

Write a method named closeEnough. The method returns a boolean value. It has 3 parameters of type double named x, y, and tolerance. If x is greater than or equal to y minus this tolerance and x is also less than or equal to y plus this tolerance, then the method returns true. Otherwise it returns false. (As a variation, consider changing the tolerance to a percentage of y and returning true if x is within that percentage of y. Test your method with positive and negative values for y.)

totally lost on this one,

Write a program to do the following. Assume that at the start of year 1, a person deposits 1000 into a savings account. At the end of the year, the bank adds 5% interest to the amount on deposit, giving 1050. At the end of the second year, the bank adds another 5% of the amount that has been on deposit, making the account 1102.50. This continues for 20 years. Write a program which uses a loop to calculate the year number (1, 2, .., 20) and the account amount for each year. The program should print the year number and the amount at the end of that year for each of the 20 years.
