In Java, a dynamic array typically refers to the ArrayList class. To assign values to a dynamic array, you can use the add() method or the set() method.<\/p>\n

    \n
  1. Use the add() method:<\/li>\n<\/ol>\n
    ArrayList<String> list = new<\/span> ArrayList<\/span><>();\r\n\r\nlist.add(\"Value1\"<\/span>);\r\nlist.add(\"Value2\"<\/span>);\r\nlist.add(\"Value3\"<\/span>);\r\n<\/code><\/pre>\n
      \n
