How to check a String value to know in its's contain the specific letter in java? -


i want check string value know if contains exact match, not characters.

i'm searching in computer

string computer = ("monitor" + "\n" + "case" + "\n" + "mouse" + "\n" + "hard" + "\n" + "vga" + "cpu");

for exact match myletter:

string myletter = "monitor";

as opposed partial match i.e. in above case "mo", should return false.

boolean state = computer.contains("mo");  boolean state = computer.contains(myletter);

i think need use word boundaries so:

     pattern p = pattern.compile(".*\\b" + myletter +"\\b.*");      matcher m = p.matcher(computer);      boolean b = m.find();       system.out.println(b);
