array in java
//method 1
int[] age = new int[3];
age[0] = 1;
age[1] = 3;
age[2] = 6;
for (int i=0; i < 3; i++)
System.out.println(age[i]);
//method 2
int[] num = {3,3,5};
//int num[] = {3,3,5}; also works the same
System.out.println(num[0]);java array
String[] cars = new String[4];
cars[0] = "Volvo";

// ! IMPORTANTE !
// in JAVA an array is not the same as an ArrayList object!!
// 1 - declare, instanciate and populate
int arr[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
// 2 - declare and instanciate an int array with maxSize
// note: the index goes between 0 and maxSize-1
int newarr[] = new int[maxSize];
// 2.1 - insert the value n on the position pos
newarr[pos] = n;
// 2.2 - insert values recursively
for (i = 0; i < maxSize; i++) { newarr[i] = arr[i]; }array in java
//Metodo 1
type nome = new type[n];
//Metodo 2
type nome[];
nome = new type[n];Copyright © 2021 Codeinu
