Question

Initialize a variable for the row, and set it to zero. Then, create a for loop from 0 to the total number or rows, then within the for loop, create a conditional that says that if the first and second entry of the array at the index of that iteration number is equal to the longitude and latitude respectively, then the value of row equals the number of the iteration. How do I do the section in bold? Here is my code so far:

public static int[] oneMonthGenerator(double longitute, double latitude, int month, double[][] drywet, double[][] wetwet) {

for (int row = 0; row < 4001; row++) {

if (longitute == drywet[row][0] && latitude == drywet[row][1]) {

row = -----> ?

} else if (longitute == wetwet[row][0] && latitude == drywet[row][1]) {

row = -----> ?

}

Expert Solution

Step 1 Given

public static int[] oneMonthGenerator(double longitute, double latitude, int month, double[][] drywet, double[][] wetwet) {

for (int row = 0; row < 4001; row++) {

if (longitute == drywet[row][0] && latitude == drywet[row][1]) {

row = -----> ?

} else if (longitute == wetwet[row][0] && latitude == drywet[row][1]) {

row = -----> ?

}

}

The above method is given in the question.

The question is to assign the number of the iteration in the loop to the variable 'row'. So in order to keep track of the number of iteration let us define another variable.

int i = 1;
