Accept a word then print every letter of that word on new line in java?

def find_all(password, File_Path):
    password = password.lower()
    with open (File_Path, 'r') as o:
        for line in o:
            if password in line.lower():
                print line[:line.find(' ')]

>>> find_all("dark", File_Path)
