JAVA second week experiment __java

1. Write a Java application that can output 26 Greek letters. Hint: We need to find the ASCII value of the first Greek letter. 2. Write a Java application, the user from the keyboard to enter the number between a 1~9999, the program will determine the number of digits, and determine whether this number is a palindrome number. Palindrome number refers to the number of numbers contained in reverse order after the number and the original number of the same, such as 12121, 3223 are palindrome number. Code appended. 3. Guess the number game. Write a Java application that implements functionality: (1) The program randomly assigns to the user a random number between 1~100 (2) Users enter their own guesses in the input dialog box (3) The program returns the prompt information, the clue information is: "Guess big", "Guess small", "guessed right" (4) The user may enter the guess again according to the prompt information, until the prompt information is "guessed right". Code appended.

		int m = (int) A;		
		for (int i=m;i<=m+24;i++)
		{		
			System.out.println ((char) i);
