you can do by using Arrays.asList

Arrays.asList(planets).indexOf("Mercury") // pass value

Arrays.asList(Rupps).indexOf("100") // pass value

or

Arrays.asList(planets).indexOf(2); //pass index

private int foundIndex(String query) {
    for (int i = 0; i < planets.length; i++) {
        if (planets[i].equals(query)) {
            return i;
        }
    }
    return -1;
}

... in code:

        int index = foundIndex("Venus");
        if(index!=-1){
            String currentRuppes =Ruppes[index]
        }
