JAVA 练习（国外英文资料） One, sequential programming 1. Input the two integer variables a, b value, output a + b, a - b, a * b, a/b, a/b (float), the result of a % b, requirements, together with the calculation output, each formula a line. Example: a is equal to 10, b is equal to 5, a plus b is lost 10 + 5 = 15 Enter a non-negative number and calculate the circumference and area of the circumference of the radius. Enter any three-digit number and output it in reverse order (for example, enter 123, output 321). Enter three integers of any size, and determine whether there are two odd or even Numbers. If the output is YES, NOT the output NOT (which requires the use of conditional expressions and NOT the if statement) Ask for the precursors and successors. Enter a character, find its precursors and successors, and print the three characters and their corresponding ASCII values in the order of ASCII values from large to small. Try the color text location output. Examples (4, 5) Enter the sides of the triangle and ask for the area of the triangle. (area = SQRT (s (s - a) (s-b) (s-c)), s = (a + b + c) / 2) Branch and circulatory programming Enter two characters, and if the difference between the two characters is even, output their subsequent characters, otherwise output their forward characters. The forward and subsequent ones here are the characters in the two characters in the input, the smaller characters in the front and the larger ones. Input integer a and b, if a can be divisible by b, output the calculation and the quotient, otherwise the output calculation, integer quotient, and remainder. 3. Enter A point A plane coordinates (x, y), judgment (output) is A point outside the circle, the circle or on the circumference of A circle, the circle from labeled (2, 2), radius of 1. Enter the year and month, and output the number of days of the month. (a year in which the leap year is judged) Output 9 * 9 multiplication tables. Ask Einstein math problem. There is a long order, if
