How to find out the adjacent word pairs from a string in java? -
i have string good
, want find out word pairs string such oo
, if string success
out put should cc ss
without using string's built in functions in java.
possible?
without any built-in method - no. 1 or 2 - can
char previous = 0; char[] chars = str.tochararray(); (int = 0; < chars.length(); i++) { if (chars[i] == previous) { system.out.println(previous + "" + previous); } previous = chars[i]; }
i prefer i < str.length()
, str.charat(i)
, uses more string
methods.
