Remove null values from string array

Why not do a for loop with if statement.

put this into the JSP but change 'array' to you array name.

<%

//go through the array to check all the values

for(int i=0; i<array.length();i++){

//If array is null, nothing happen

if(array==null){

//leave here blank

}

//If array not null, then print value in a new line

else{

out.print(array+"<br>");

}

}

%>

Does that help?

>Thank you but because I am new in programming what do you mean to use continue. Can you explain it a little bit further?

<%

//go through the array to check all the values

for(int i=0; i<array.length();i++) {

//If array is null, nothing happen

if(array==null){

//leave here blank; instead use continue like:

//this will skip the statements next to it, and increments the value of i in for loop and continues to execute the body of for loop.

//The same will be repeated till the last iteration.

continue;

}

//If array not null, then print value in a new line

else{

out.print(array+"<br>"); //don't change the logic here

}

}
