I have some code here
String array[]=new String[5];
for(int i=0;i<array.length;i++){
array[i]= "item "+String.valueOf(i);
i++;
}
and this is log message what i got after application crash
java.lang.IndexOutOfBoundsException : Invalid array range: 5 to 5
Could you guys explain me why pls ? I just want to declare an array and use for loop to initialize array element, just dont know why my code didn't work . Thank you
because key index More increases than index array in your loop .
String array[]=new String[5];
for(int i=0;i<array.length;i++){
array[i]= "item "+String.valueOf(i);
}
remove extra i++.. it already redundant except you have some purpose to do so.
String array[]=new String[5];
for(int i=0;i<array.length;i++){
array[i]= "item "+String.valueOf(i);
//i++; //remove this.. it already redundant except you have some purpose
}
its java.lang.IndexOutOfBoundsException : Invalid array range: 5 to 5 because of the counter already exceed size of your string which 5 only..
use ArrayList instead
Just do this:
String array[]=new String[5];
for(int i=0;i<array.length;i++){
array[i]= "item "+String.valueOf(i);
}
That second i++ was causing your index out of bounds.
Don't increment the 'i' value twice, which is causing this issue.
String array[]=new String[5];
for(int i=0;i<array.length;i++){
array[i]= "item "+String.valueOf(i);
//i++; //remove this..
}
Instead of using Array[] you can you Collections such as ArrayList<String> or List<String>.
i++. Why?
