How can I set a flag value in an array loop?

I have an array as shown below.

Basically in this array, sometimes thebagdata[i].getSecurityType() may or may not contain values in an array.

 for (int i = 0; i <bagdata.length; i++) {
                if (bagdata[i].getSecurityType() != null) {
                    flag = true;
                } else {
                    flag = false;
                }

            }

I think that my code is overriding the flag value. How can I deal with this?

If you the flag value to be set true then come out of the loop using break statement.

If you want to set flag to true if at least one containsdata you should just set the flag to false before the loop and delete part of else like this:

        flag=false;
          for (int i = 0; i <bagdata.length; i++) {
            if (bagdata[i].getSecurityType() != null) {
                flag = true;
            }
        }

but if you want to remember flag for each element in array you should create an array of flags...

Use break; immediate after setting the flag if required. If you want flag against each value, make an array of flags.

Depend on what you want to flag, try:

boolean flag = true;

for (int i = 0; i <bagdata.length; i++) {
    flag &= bagdata[i].getSecurityType() != null;
}
