Using a recursive is simpler, give you a small example

 static String [] CHAR=new String [] {" a ", "b", "c", "d", "e", "f", "g", "h", "I", "j"}; 
Public static void print (String STR) {
If (STR) length ()==4) {
System. The out. Println (STR); 
return; 
} 
For (String s: CHAR) {
Print (STR + s); 
} 
} 
Public static void main (String [] args) {
Print (" "); 
}
