I\'ve got a nested loop construct like this:

for (Type type : types) {
    for (Type t : types2) {
         if (some condition) {
             // Do somethin

    Java 8 Stream solution:

    List types1 = ...
    List types2 = ...
    
    types1.stream()
          .flatMap(type1 -> types2.stream().map(type2 -> new Type[]{type1, type2}))
          .filter(types -> /**some condition**/)
          .findFirst()
          .ifPresent(types -> /**do something**/);
