  3. Declaring arrays in Java O int arr[5]; //error O int arrl: int arr[]; int [] arr = new int[5]; int arr[] =new int[5]; int [ arr new in[5];


  4. Initializing during declaration int arrll-new int[l (2,4, 6, 8, 10]; int ari-new int[2] {2, 4, 6, 8, 10); //error int arr[]=new.nt[5](2,3,4,5,8); //error: you can not mention size and values together int arrll (2, 4, 6, 8, 10];


  5. Array is not blank int [larr-new int[3]; System.out.printin("arr[01:4arr[0]); arr length 3


  6. Find Error public class ArrayExample public static void main(String args[I) int arrll; arr[0]=25; arr 1] =50;


  7. Error public class ArrayExample public static void main(String args[I) Compile time error arr is blank int arr: arr[0]=25; arr(11-50; arr local variables when not initialized, they are blank


  8. Initialization after declaration public class ArrayExample public static void main(String args]) int arrl arr = new int[3]; arr new int[3]; arr[0]-10; arr[1]-20; arr[2]=30;


  9. User input import java.util. class ArrayExample1 public static void main(Stringl] args) import java.util.*; arr[o]-10 arr[1]-20 arr[2] = 30 arr[3]-40 arr 41-50 public static void main(Stringll args]-20 int []arr=new int[5]; Scanner sc-new Scanner(System.in); System.out.println("Enter 5 numbers" for(int i=0;i<5;i++) arr[i]=sc.nextlnt(); for(int i=0;i<5;i++) System.out.printIn(''arr(''th" 4arr[i]);
