Sort the array in ASC and DESC


Sort the array in ASC and DESC

a = {1, 4, 5, 7}:

1.After sorting in ascending order using Arrays.sort(a), the array becomes a = {1, 4, 5, 7}.

2.Array Sorting: The Arrays.sort(a) method is used to sort the array a in ascending order.

3.Printing Sorted Array: The sorted array is then printed to the console using System.out.println(Arrays.toString(a)).

4.Reversing Array (Descending Order): A new array named descendingorder is created to store the reversed (descending) order of the sorted array. A loop is used to iterate through the sorted array and populate the descendingorder array in reverse order.


Let's apply this with the current values:

  • When i = 0, descendingOrder[0] = a[4 - 1 - 0] = a[3] = 7.
  • When i = 1, descendingOrder[1] = a[4 - 1 - 1] = a[2] = 5.
  • When i = 2, descendingOrder[2] = a[4 - 1 - 2] = a[1] = 4.
  • When i = 3, descendingOrder[3] = a[4 - 1 - 3] = a[0] = 1.

5.Printing Reversed Array: The reversed array is then printed to the console using System.out.println(Arrays.toString(descendingorder)).

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 ).

"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.

Reversing the String ; Doubling Each Letter

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...
