Copy array into another array many times in java -

i wanted copy array 1 integer array array many times.

int a[6]={1,2,3}; int b[]=new int[12]; for(int i=0;i<12;i++) { b[i]=a[i]; system.out.println(b[i]); }

i wanted output this:

1,2,3,1,2,3,1,2,3,1,2,3

how should copy element a[] b[] many times want.

you can use modulus operator :

for(int i=0;i<12;i++) {     b[i]=a[i%a.length];     system.out.println(b[i]); }

i%a.length iterate repeatedly 0 a.length-1.
