Java Training in Chennai – Arrays – Learning – Part – II
Here in this blog we are going to discuss about Java Training in Chennai – Arrays – Learning – Part – II . They are illustrated very well below .
We have already discussed about some programs in the previous blog “Java Training in Chennai – Arrays – Learning “

What will be the output of the following program?

System.out.println(AssertionError);
}
}
What will be the output of the following program?
public class DemoOnArrays

public static void main(String args[])
{
int[] firstInput, secondInput;
firstInput = new int[2];
secondInput = 011;
firstInput[0] = firstInput[1] = secondInput;
System.out.print(firstInput[0] + firstInput[1]);
}
}
