Accessors and Mutators in JAVA

Accessors:
API's or methods which were used to get the current state of an object.

Mutators:
API's or methods which were used to change the state of an object.
Ex: set(int a);

An object has mainly two things state and behaviour.. State denotes the instance variables of a class and Behaviour denotes the methods or API's in class[ which is blueprint of an object] .
class Animal{
private int color;

  public void getColor(){
  return color;
  }
public setColor(int color){
this.color = color;
}
}

In this program, getColor is an Accessor setColor is Mutator

Internet Explorer Users have low IQ

On average, Internet Explorer used were far than worst, where IE6 users were at the bottom. However, IE8 users performed slightly better. Other well known browsers like Firefox, Chrome and Safari were in the middle of the list and had small differences among them. Camino and IE with Chrome Frame were on top along with Opera. These users had the best average score.

In 2006, the same study says that IE was performing well. So this study may not be true.

Can you make out 37 using five 5's

The Solution is very simple..

2^5 =32. To get 2, we can use ((5+5)/5)

So the answer is

Hot Water in WaterBottle

Usually we used to have a water bottle in office desks. We fill water in the morning. On a Monday morning, i found one of my friends bottle in the pantry and he used to drink only hot water. So i washed that bottle with cold water and filled it completely with hot water and carried to his desk. He thanked me for this activity at start. After few minutes, he felt thirsty and he drank  the water from the bottle. Suddenly he spitted the water on the floor and he started scolding me that Water is too hot.
I didn't realize that the water would be so hot. Even his water bottle would be like a flask not a plastic one.
