All combination of string

Question

consider an array of items:
String l1[]={a,b,c,d,e,f},how can we generate all combination of this set,which contains output as follows:
c2[]={a a,a b,a c ,a d, a e,a f,aa,ab,ac,ad,ae,af,ba,bb,bc,bd,be,bf,...........}
can any one suggest logic of doing this in java

Answer 1

hi learner,
String a[] = {"a","b","c"};
String c[] = new String[a.length * a.length];
for(int i=0,k=0; i<3; i++)
for(int j=0;j<3;j++,k++)
c[k] = a[i]+a[j];
for(int i=0;i<c.length;i++)
System.out.println(c);
this is the solution you need.... right
