Deleting files and etc on your computer.
D)When the query is run again, the data that meets the new criteria will be retrieved.
Answer:
int[ ][ ] X = new int[5][5];
It can also be declared and initialized this way:
int[][] X = {
{1,2,3,6,8},
{4, 5, 6, 9},
{7,5,6,8,9},
{8,5,8,8,9},
{10,2,6,8,11},
};
Explanation:
Above is a declaration of a two-dimensional array that can hold 5*5=25 int values. A java program is given below:
public class JavaTwoD{
public static void main(String args[ ]) {
// creating the 5X5 array
int[ ][ ] X = new int[5][5];
// looping through the array to add elements
for (int i = 0; i < X.length; i++) {
for (int j = 0; j < X[i].length; j++) {
X[i][j] = i * j;
}
}
