Message:

Use contains ( ) method

Posted by Kishori Sharan on February 18, 2001 at 3:42 PM

Suppose you are going to add an element e1 in a vector v1 and before adding you want to know if e1 already exists in the vector v1 then you can use contains() method of vector as

if ( v1.contains ( e1 ) ) {
// e1 already exists in v1
}
the contains method returns true if e1 is already there in v1 else it returns false.
