Answer 1

Kim Jonas Cabugayan

public static void printArray(char[] arr) {
//write your code here

}

Now call this method inside main method

public static void main(String[] args) {

char[] arr = {'a', 'b'};

//Calling method
printArray(arr);
}

Answer 2

Just make a method and put for loop code inside that then call that method in main method.

You can pass an array as an arguments in that method

Answer 3

Yes void doesn't return anything so you can not print method like that.

do this

System.out.println("***");
printArray(arr1);
System.out.println("***");

/*I tried replacing void with char[]
but I don't know what to place between
return ;
*/
class A {

public static void printArray(char[] arr) {
for (int i=0; i<arr.length; i++){
System.out.println("*" + arr[i] + "*");

}

}

public static void main(String[] args) {

char[] arr1 = {'a', 'b'};
System.out.println("***" + printArray(arr1) + "***");

}
}

//void type is not allowed

Answer 12

Count the character sequence of a string element.

Add asterisk depending in the total no. counted.

i.e {"Mozzie"} (6)
******
Mozzie
******

{"Moon"} (4)
****
Moon
****

and use the highest value
{"Mozzie", "Moon"}
******
Mozzie
Moon
******

Why there's no error at line 23 at your code?
Isn't it supposed to ask for identifier?

Answer 14

Identifier for what?

Answer 15

Before if I used

System.out.println();

It always run into error then ask for identifier.
But it suddenly okay now don't know what happened there😅😅
