ArrayList<String> languages = new ArrayList<String>();
languages.add("Java");
languages.add("PHP");
languages.add("HTML");
languages.add("Python");
languages.add("PhotoShop");
languages.add("C++");
System.out.println(languages); //[Java, PHP, HTML, Python, PhotoShop,C++]
System.out.println(languages.subList(1,4)); //[PHP, HTML, Python]

If we use startIndex and endIndex same then we will get blank output.

System.out.println(languages.subList(1,1)); //[]

If we use endIndex more less thean startIndex,

System.out.println(languages.subList(2,1)); // error

If you use boyond the last element index then we will get java.lang.IndexOutOfBoundsException

System.out.println(languages.subList(1,10)); // error
