public static void main(String args[]) {

//limitations of array:

//1. size is fixed: static array : to overcome this problem, we use dynamic array or ArrayList

//2. stores similar types of values: to overcome this problem, we use dynamic array or Object array

//1. int:

int i[] = new int[4];

i[0]=10;

i[1]=20;

i[2]=30;

i[3]=40;

System.out.println(i[1]);

System.out.println(i[0]+i[1]);

System.out.println(i.length); //size of array

//System.out.println(i[4]); //ArrayIndexOutOfBoundsException

//to print all the values of array: use for loop:

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

System.out.println(i[k]);

}

//2. double:

double d[] = new double[2];

d[0]=12.33;

d[1]=12.44;

System.out.println(d[0]+d[1]);

//3. char:

char c[] = new char[2];

c[0]='a';

c[1]='$';

//4. boolean:

boolean b[] = new boolean[2];

//String:

String []s = new String[2];

s[0]="Hello";

s[1]="World";

System.out.println(s[0]+s[1]);

//Object Array:

Object ob[] = new Object[5];

ob[0]="Tom";

ob[1]=25;

ob[2]='M';

ob[3]="London";

ob[4]=12.33;

}

}
