Getting started example code from the gridgain docs

gistfile1.java

try (Grid g = GridGain.start()) {
    Collection<GridCallable<Integer>> calls = new ArrayList<>();
 
    // Iterate through all the words in the sentence and create Callable jobs.
    for (final String word : "Count characters using callable".split(" ")) {
        calls.add(new GridCallable<Integer>() {
            @Override public Integer call() throws Exception {
                return word.length();
            }
        });
    }
 
    // Execute collection of Callables on the grid.
    Collection<Integer> res = g.compute().call(calls).get();
 
    int sum = 0;
 
    // Add up individual word lengths received from remote nodes.
    for (int len : res)
        sum += len;
 
    System.out.println(">>> Total number of characters in the phrase is '" + sum + "'.");
