vector - ArrayList and more primitive types togheter in Java -

i need create java array list (precisly, vector) contain more 1 primitive types. example, see in every vector's row this:

row[0] --> "str1", 5, "str2", "str3", 3.5, 6, "str4"...etc... row[1] --> "str5", 6, "str6", "str7", 5.3, 8, "str8"...etc... 

can me?

thanks!! :)

i think solution problem. made code works integer, string , float (the rest u can finish).

main (with yours values)

public static void main(string[] args) {         //init         arraylist<arraylist<something>> mainlist = new arraylist<>();         arraylist<something> sublist1 = new arraylist<>();         arraylist<something> sublist2 = new arraylist<>();         //fill array lists         sublist1.add(new something("str1", 0));         sublist1.add(new something(5, 1));         sublist1.add(new something("str2", 0));         sublist1.add(new something("str3", 0));         sublist1.add(new something(3.5f, 2));         //etc         sublist2.add(new something("str5", 0));         sublist2.add(new something(6, 1));         sublist2.add(new something("str6", 0));         sublist2.add(new something("str7", 0));         sublist2.add(new something(5.3f, 2));         //etc         //add 2 list in main         mainlist.add(sublist1);         mainlist.add(sublist2);         //iterator         int = 0;         (arraylist<something> sublist : mainlist) {             i++;             system.out.println("results list " + i);             (something : sublist) {                 switch (something.gettype()) {                     case 0: {                         system.out.println("string value: " + (string) something.getvalue());                         break;                     }                     case 1: {                         system.out.println("integer value: " + (integer) something.getvalue());                         break;                     }                     case 2: {                         system.out.println("float value: " + (float) something.getvalue());                         break;                     }                   }             }         }      } 

class something:

public static class {          private object value;         private int type;          /**          * constructor of class          *          * @param value          * @param type type 0 string <br/>          * type 1 integer <br/>          * type 2 float ....          */         public something(object value, int type) {             this.value = value;             this.type = type;         }          public object getvalue() {             return value;         }          public void setvalue(object value) {             this.value = value;         }          public int gettype() {             return type;         }          public void settype(int type) {             this.type = type;         }      } 

output of main:

results list 1 string value: str1 integer value: 5 string value: str2 string value: str3 float value: 3.5 results list 2 string value: str5 integer value: 6 string value: str6 string value: str7 float value: 5.3
