JsonDemo.java

package com.tutorialspoint;

import org.json.JSONArray;

public class JsonDemo {
   public static void main(String[] args) { 
      JSONArray list = new JSONArray();

      list.put("Apple");
      list.put("Banana");
      list.put("Orange");
      list.put("Mango");
      list.put("Guava");

      System.out.println("JSONArray: ");
      System.out.println(list);
   }
}

Output

JSONArray: 
["Apple","Banana","Orange","Mango","Guava"]

Example - JsonArray of Integers

JsonDemo.java

package com.tutorialspoint;

import org.json.JSONArray;

public class JsonDemo {
   public static void main(String[] args) { 
      JSONArray list = new JSONArray();

      list.put(Integer.valueOf(100));
      list.put(Integer.valueOf(200));
      list.put(Integer.valueOf(300));
      list.put(Integer.valueOf(400));
      list.put(Integer.valueOf(500));

      System.out.println("JSONArray: ");
      System.out.println(list);
   }
}

Output

JSONArray: 
[100,200,300,400,500]

Example - JsonArray of Mixed Types

JsonDemo.java

package com.tutorialspoint;

import org.json.JSONArray;
import org.json.JSONObject;

public class JsonDemo {
   public static void main(String[] args) { 
      JSONArray list = new JSONArray();

      list.put("foo");
      list.put(Integer.valueOf(100));
      list.put(Double.valueOf(1000.21));
      list.put(Boolean.TRUE);
      list.put(JSONObject.NULL);

      System.out.println("JSONArray: ");
      System.out.println(list);
   }
}

Output

JSONArray: 
["foo",100,1000.21,true,null]
