How do I print the second last element of an array?
Step 1: Use split() Method to split the elements into an array. var fragment_arr = fragment. split(“/”); Step 2: Use slice(-2) Method to select last 2 element from array, the negative number to select from the end of an array.
How do I get the second last element in a list?
Any element in list can be accessed using zero based index. If index is a negative number, count of index starts from end. As we want second to last element in list, use -2 as index.
How do you access the last element of an array in Java?
Approach:
- Get the ArrayList with elements.
- Get the first element of ArrayList with use of get(index) method by passing index = 0.
- Get the last element of ArrayList with use of get(index) method by passing index = size – 1.
How do you print last but one element in a list Python?
“how to get last but one element in set by index” Code Answer
- number_list = [1, 2, 3]
- print(number_list[-1]) #Gives 3.
- number_list[-1] = 5 # Set the last element.
- print(number_list[-1]) #Gives 5.
- number_list[-2] = 3 # Set the second to last element.
- [1, 3, 5]
How we access the 7th element stored in an array?
4. Which of the following accesses the seventh element stored in array? Explanation: The array location starts from zero, So it can accessed by array[6]. So as we need address of first index we will use (arr + 0) equivalent to arr.
How do you print the last two elements of a list in Python?
Use slicing to get the last n elements of a list. Use the slicing syntax list[-n:] to get a list containing the last n elements of list .
How do I print a specific element in an ArrayList?
PRINTING ARRAYLIST
- 1) Using for loop. //using for loop System.out.println(“Using For Loop\n “); for (int i = 0; i < arrlist.size();i++) { System.out.println(arrlist.get(i)); }
- 2) Using for-each loop.
- 3) Using iterator.
- 4) Using list-iterator.
How do I print a single element in an array?
You can access an array element using an expression which contains the name of the array followed by the index of the required element in square brackets. To print it simply pass this method to the println() method.
How do you print an array of elements in Java?
Methods To Print An Array In Java. There are various methods to print the array elements. We can convert the array to a string and print that string. We can also use the loops to iterate through the array and print element one by one.
How to get the last element of a string in Java?
String sentence = “Any simpler way to get the last element of a Java array?”; String [] tokens = sentence.split (” “); String lastToken = tokens [tokens.length-1]; It’s awkward, but there’s really no other way to do it unless you have foreknowledge of the length of the string.
How to print two-dimensional arrays in Python?
‘deepToString’ that is used to print two-dimensional arrays is similar to the ‘toString’ method which we discussed earlier. This is because if you just use ‘toString’, as the structure is array inside the array for multidimensional arrays; it will just print the addresses of the elements.
How do you print an array in order in algorithm?
Algorithm 1 START 2 INITIALIZE arr [] = {1, 2, 3, 4, 5} 3 PRINT “Original Array:” 4 REPEAT STEP 5 for (i=0; i<arr.length ; i++) 5 PRINT arr [i] 6 PRINT “Array in reverse order” 7 REPEAT STEP 8 for (i= arr.length-1; i>=0; i–) 8 PRINT a [i] 9 END
