"Java Programming: Arrays, Methods, and Stream API"

Main  Method 'main'

Step 1: This is the main method or starting point of the program.

Step 2: I declared StudentA as a array name and initialized their value value{100,98,..}.

Step 3: The 'Arraysum' Method is called with with StudentA and result will stored in the sum name as a integer.

Step 4: print the sum. 


'Arraysum' Method

Step 5: Arraysum method takes an array of integers int[] studentA  as a parameter and returns an integer.

Step 6: Iteration have started here , Instead for loop and used stream operation to reduce the lines and more readable.

Swabbing Tow no's

  Method 1: Using a Temporary Variable (commented out): This is a traditional approach using a temporary variable t to store the value of b before swapping. It then swaps the values of a and b using the temporary variable Method 2: Without Using a Temporary Variable: This is a mathematical approach to swap the values without using a temporary variable. It leverages the fact that a = a + b adds the values of a and b , b = a - b subtracts the original value of b from the sum (resulting in the original value of a ), and a = a - b subtracts the new value of b (original value of a ) from the sum (resulting in the original value of b ).

Step 1: Create a Scanner object to take user input Scanner Initialization: Create a Scanner object named scanner to take user input from the console. Step 2: Prompt the user to enter a name User Input: Prompt the user to enter a name using System.out.println("Enter the name:"); and Step 3: Read the user input (name) using the Scanner Read the input using String name = scanner.next(); Step 4: Display the original name Display Original Name: Print a message indicating that the entered name is going to be displayed. Step 5: Reverse the input string using StringBuilder Reverse the Name: Use StringBuilder to reverse the input string (StringBuilder(name).reverse()). Step 6: Display the reversed name Display Reversed Name: Print the reversed name Step 7: Create a new StringBuilder to store the doubled name Step 8: Iterate through each character in the reversed name Double Each Letter: Iterate through each character in the reversed name and append it twice to a new StringBuilder (dou...
