Question

How to iterate through int[][] numarr={{1,2,3},{4,5,6,7},{8,9}};?

a) Nested for loop
b) While loop
c) Single for loop
d) Do-while loop
e) For-each loop

Answer 1

To iterate through a 2D integer array numarr={{1,2,3},{4,5,6,7},{8,9}};, you can use a nested for loop.

Step-by-step explanation:

To iterate through a 2D integer array int[][] numarr={{1,2,3},{4,5,6,7},{8,9}};, you can use a nested for loop.

This allows you to iterate through each element in the array, both rows and columns.

Below is an example of how you can use a nested for loop to iterate through the numarr array:

for (int i = 0; i < numarr.length; i++) { for (int j = 0; j < numarr[i].length; j++) { System.out.println(numarr[i][j]); } }
