I need help on JAVA

I need to use String target and Source as parameter and return boolean

when target is within source true, otherwise false.

I used Scanner and searching loops but there somehting wrong.

I need advise and right example to solve this question

public static boolean containsToken.String..t...String.s). boolean containsfalse; Scanner scnt - new Scanner(t); String target scnt.next); Scanner scnsnew Scanner(s); String source scns.next); while (scns.hasNext )) if (source.contains(target)) f return true; else return false
