It is important to know this example that is, How to merge both array in single variable !!!!

Below program provide you the reference regarding merging both array in other ! 

_______________________________________


public class Array {


public static void main(String[] args) {
// TODO Auto-generated method stub

int A [] = {1,2,3,4,5};

int B [] = {6,7,8,9,10};

int C[][] = {A,B}; 


int la = A.length;
int lb = B.length;




System.out.print("ARRAYS in A: ");

for(int x = 0; x<la;x++){
System.out.print("  "+A[x]);
}



System.out.println(" \n");



System.out.print
("ARRAYS in B: ");


for(int y=0;y<lb;y++){
System.out.print(" "+B[y]);
}



System.out.println("\n ");




System.out.print("Arrays in C: ");

for(int i = 0; i<C.length;i++){

for(int j= 0;j<C[i].length;j++){
System.out.print(C[i][j]);
}
     }
}
}

_______________________________________

Output:

ARRAYS in A:   1  2  3  4  5 

ARRAYS in B:  6 7 8 9 10

Arrays in C: 12345678910

________________________________________

In above programme, we use two dimensional array C[] []  to merge the A[] and B[] single array !!!

Hope you enjoy this simple but important programme !
