In if-else construct which part will be executed if condition is ture in Java ?

In an if-else construct in Java, the code within the if block will be executed if the condition specified in the if statement is true. If the if condition is false, then the code within the else block (if an else block is provided) will be executed.

Programming Code:

Following code write in: DS_P20.py

# Python Program / Project 

def bucketsort(arr):
    bucket = []
    maxe = max(arr)
    size = maxe/len(arr)

    # Create empty bucket
    for i in range(len(arr)):
        bucket.append([])

    # Insert elements into their respective 
    for i in range(len(arr)):
        j = int (arr[i]/size)
        if j!= len(arr):
            bucket[j].append(arr[i])
        else:
            bucket[len(arr)-1].append(arr[i])

    # Sort the elements of each bucket
    for i in range(len(arr)):
        bucket[i] = sorted(bucket[i])
    
    # Get sorted elements
    k = 0
    for i in range(len(arr)):
        for j in range(len(bucket[i])):
            arr[k] = bucket[i][j]
            k += 1
    
    return arr

# Driver Code

num = int(input("Enter how many students in 12 class:"))
arr = []

i = 0
for i in range(num):
    item = float(input("Enter percentage marks: "))
    arr.append(item)

print("Before sorting percentage list: ")
print(arr)

bucketsort(arr)
print("After sorting using Bucket Sort list is: ")
print(arr)

print("Top five percentage marks: ")
for i in range(len(arr)-1, 1, -1):
    print(arr[i])
