Ruby program to push an array into another array

arr1 = [101,102,103,104,105];
arr2 = [106,107,108,109,110];

arr1.push(arr2);

print "Array elements: \n";

i=0;

while(i<arr1.length())
    print arr1[i],"\n";
    i = i + 1;
end

Output:

Array elements: 
101
102
103
104
105
[106, 107, 108, 109, 110]
