Here is the Output.

In this program two number is entered by the user and greatest among then are printed.

I have discussed What is Java and For what it is used.

I have discussed How Java is different from other programming languages and How it works.

I have discussed Features of Java Programming Language.

In this program a number is accepted by the user and reversed. If user Input: 123 then Output: 321.

In this program an integer is accepted by the user and checked whether it is Armstrong Number or not.
An Armstrong number is a number such that the sum of its digits raised to the third power (i.e. n^3) is equal to the number itself.
For Example: Input: 153, Output: 153 is an Armstrong Number.
Since, 1^3+5^3+3^3 = 153 or 3^3+5^3+1^3 = 153.

Here is the Output.

In this program an integer is inputed by the user and checked whether it is a Palindrome Number or not.
A palindromic number is a number that remains the same when its digits are reversed.
For Example: Input: 121 Output: 121 is a Palindrome Number.
