# Java

> Run Java snippets through the code interpreter Java kernel.

The standard `code-interpreter` template includes a Java Jupyter kernel.

  ```python Python SDK theme={"theme":{"light":"one-light","dark":"one-dark-pro"}}
  result = machine.run_code("""
  int total = 0;
  for (int value : new int[] {1, 2, 3}) {
      total += value;
  }

  """, language="java")

  print(result.results[0].text)

  ```typescript TypeScript SDK theme={"theme":{"light":"one-light","dark":"one-dark-pro"}}
  const result = await machine.code.run(`
  int total = 0;
  for (int value : new int[] {1, 2, 3}) {
      total += value;
  }
  total

  console.log(result.results[0].text);

  # returns a Server-Sent Events stream of JSON events
  curl -N -X POST "${NULLSPACE_API_URL}/v1/machines/mch_123/code/execute" \

Use Java contexts for snippets that should share definitions across executions.
