public void findAbc(String input){ int index = input.indexOf("abc"); while (true){ if (index == -1 || index >= input.length() - 3){ break; }

After the program finds the 2nd occurrence of abc, at what index does it start searching for the 3rd occurrence?

Hint: look at the line index = input.indexOf("abc",index+4);

String found = input.substring(index+1, index+4); System.out.println(found); index = input.indexOf("abc",index+4); } }

public void test(){ //findAbc("abcd"); findAbc("abcdabc"); }
