I can study java code but i have a problem

Question

i can do individual code but how would i put for example a do while loop into a regular array? i have trouble putting code together without a bunch of errors. unfortunatley i don't know what the errors mean.

Answer 1

The best form of learning when it comes to coding is practice. Writing your own programs will help you study.
As far as a do while in an array, that question is to vague. But i'll assume you just mean filling the array with values from, lets say, 0-9.

This is with the do-while loop (Keep in mind, you should actually just use a for loop for this).

int index = 0;
int[] array = new int[10];

do{
array[index++] = index;
// fills the array
}while(index <= 9);

Once you get the hang of these loops, it'll look like a piece of cake (only with far less calories).
Keep Trying! 😀

Your code seems to work as it is, but I am assuming based on your post that you were trying to implement a do while loop. I would say a for:each loop looks a lot cleaner for what you are trying to do, so I implemented both that and a do while loop in the code below.

public class Background {
public static void main(String []args){
String [] mynames = {"A","B","C","D","E","F"};
/*System.out.println(mynames[3]);
System.out.println(mynames[0]);
System.out.println(mynames[3]);*/
for(String name : mynames){
System.out.println(name);
}
int x = 0;
do{
System.out.println(mynames[x]);
x++;
}
while(x < mynames.length);
}
}

If you have any other question I would be happy to answer.

Here is code for creating an array in a do-while as well:

public class Background {
public static void main(String []args){
String [] mynames = {"A","B","C","D","E","F"};
String alpha = "abcdefghijklmnopqrstuvwxyz";
char[] mynames1 = new char[26];
int i = 0;
do{
mynames1[i] = alpha.charAt(i);
i++;
}
while(i < mynames1.length);
/*System.out.println(mynames[3]);
System.out.println(mynames[0]);
System.out.println(mynames[3]);*/
for(char name : mynames1){
System.out.println(name);
}
int x = 0;
do{
System.out.println(mynames[x]);
x++;
}
while(x < mynames.length);
}
}

Answer 4

Could you please provide an example of the code you are having difficulties with? I am not quite sure what you mean by putting "a do while loop into a regular array", as an array is a data type and can not contain loops. If you post code, however, I would be happy to help sort out whatever errors you are running into.
