Definitely A.
Can someone explain me the second part of this?
I don’t understand what for(String[]ca: chs)… and the other one check for?
Why run these loop three times?
Please help 🙂
Answer: A
Tested
a
public static void main(String args[]){
String[][] chs = new String[2][];
chs[0] = new String[2];
chs[1] = new String[5];
int i = 97;
for (int a = 0; a < chs.length; a++){
for (int b = 0; b < chs.length; b++){
chs[a][b] = "" + i;
i++;
}
}
for (String[] ca : chs) {
for (String c : ca){
System. out. print (c + " ");
}
System.out.println();
}
}
97 98
99 100 null null null
