Arrays

Arrays:

• An Array is a collection of similar type of elements
• The advantage of array is we can represent multiple values under the same name
• once we create an array there is no chance of  increasing\decreasing the size of an array 
• we can resolve this problem using collections

Program on Array

class ArrayDemo{  

public static void main(String args[]){  

  int a[]=new int[6];//declaration and instantiation  

a[0]=10;//initialization  

a[1]=20;  

a[2]=70;  

a[3]=40;  

a[4]=50;

a[5]=60; 

  //printing array  

for(int i=0;i<a.length;i++)

System.out.println(a[i]);  

  }}  

output: 

10

20

70

40

50

60
