How do I see if a substring exists inside another string in Java 1.4?

Question

How can I tell if the substring "template" (for example) exists inside a String object?

It would be great if it was not a case-sensitive check.

Answer 1

String.indexOf(String)

For a case insensitive search, to toUpperCase or toLowerCase on both the original string and the substring before the indexOf

String full = "my template string";
String sub = "Template";
boolean fullContainsSub = full.toUpperCase().indexOf(sub.toUpperCase()) != -1;
