Is Editable() is used to determine whether a combo box is editable or not.

Following are the basic postulates of Boolean algebra:

(1) If X not equal to 0 then X equal to 1; and If X not equal to 1 then X equal to 0 

(2)  OR Relations (Logical Addition)

(i)  0 + 0 = 0

(ii)  0 + 1 = 1

(iii)  1 + 0 = 1

(iv) 1 + 1 = 1

(3) AND Relations (Logical Multiplication) 

(i) 0 . 0 = 0  (ii) 0 . 1 = 0  (iii) 1 . 0 = 0  (iv) 1 . 1 = 0 

(4)  Complement Rules

(i)  0’ = 1  (ii)   1’= 0

Layout manager is a way to control arrangement, position and size of visual components on a GUI form.

(i)  AB + AB’ + A’C + A’C’ 

= A(B + B’) + A’(C + C’)    (B + B’ =1, C + C’ = 1)

= A + A’ (A + A’ = 1) = 1

(ii)  XY + XYZ’ + XYZ’ + XZY 

= XY(Z’) + XY(Z’ + Z) (Z + Z’ =1) 

= XY(Z’) + XY = XY(Z’ + 1) (Z’ + 1 = 1) 

= XY

(iii)  XY(X’YZ’ + XY’Z’ + XY’Z’) 

= XY[Z’(X’Y + XY’ + XY’)] 

= XY[Z’(X’Y + XY’(1 + 1)] 

= XY[Z’(X’Y + XY’)] 

= XYZ’(X’Y + X Y’)

(a)  X + X’Y + X’Y’ 

= X(Y + Y’)(Z + Z’) + X’Y(Z + Z’) + X’Z’(Y + Y’) 

= (XY + XY’)(Z + Z’) + X’YZ + X’YZ’ + X’YZ’ + X’Y’Z’ 

= Z(XY + XY’) + Z’(XY + XY’) + X’YZ + X’YZ’ + X’YZ’ + X’Y’Z’ 

= XYZ + XY’Z + XYZ’ + XY’Z’ + X’YZ + X’YZ’ + X’YZ’ + X’Y’Z’ 

By removing duplicate terms we get canonical Sum-of=Product form : 

XYZ + XY’Z + XYZ’ + XY’Z’ + X’YZ + X’YZ’ + X’Y’Z’

F = ∑(1, 2, 3, 4, 5, 6, 7)

F = m1 + m2 + m3 + m4 + m5 + m6 + m7 

(b)  YZ + X’Y 

= YZ(X + X’) + X’Y(Z + Z’) 

= XYZ + X’YZ + X’YZ + X’YZ’ 

By removing duplicate terms we get canonical Sum-of=Product form : 

XYZ + X’YZ + X’YZ’ 

F = ∑(2, 3, 7)

F= m2 + m3 + m7

• The statements which can be determined to be True or False are called logical statements or truth functions. 
• The result TRUE or FALSE are called truth values.
• Both ‘truth table’ and ‘truth function’ are related in a way that truth function yields truth values. 

(i) X + YZ + XZ

= (X + YZ + XZ)’ 

= (X)’(YZ)’(XZ)’

= X’(Y’ + Z’)(X’ + Z’)

(ii) AB(C’D + B’C)

= (AB)’(C’D + B’C)’

= (AB)’((C’D)’ + (B’C)’)

=(AB)’(CD’ + BC’)

=(A’ + B’)+(C + D’)(B + C’)

A container component is a special type of component that can hold other components. Some swing containers are JPanel, JFrame etc.

•  Event is an occurrence of an activity. 
•  Event handler is a method that understands the event and processes it. The event handler method takes the event object as a parameter.

•  A button group is a group control out of which only one can be selected at a time. 
•  A button group is created through JButtonGroup component class of java Swing. In a button group we can put radio buttons or push buttons. Although checkboxes can also be put in a button group but it is not recommended.

Do Click() method can programmatically mimic the click action of a push button.

More stable is the conjugate base, stronger will be the acid. R-O- is less stable ,due to +I effect of alkyl group, due to the intensification of charge. Since -OH - > -OR - , hence water is more acidic than alcohols.

Water is more acidic than alcohols.

 This is because the OH group in alcohols is less polar than the OH group in water. The electron releasing nature of the R group in alcohols decreases the polarity of the OH bond, leading to a decrease in acid strength of alcohols. As a result, water is a better proton donor than alcohol. Also, the alkoxide ion is a better proton acceptor than the hydroxide ion, suggesting that the alkoxides are stronger bases.

Work done by the block on spring, W=mgh =1/2kx²  

By using the above formula you can get the answer 

The circulatory system in human beings consists of heart, blood vessels (arteries, veins  and capillaries) and blood. Blood circulates throughout the body in blood vessels by the  pumping action of the heart. The impure blood is carried by veins from all parts of the  body to the heart. The heart pumps it into the – lungs where blood is oxygenated and  carried back to the heart. From heart, the oxygenated (pure) blood is pumped to all  parts of the body through arteries.  

Thus, the circulatory system forms the transport system carrying food, oxygen, waste  products, nutrients etc. throughout the body.

Blood is a mixture of cells and plasma. The heart pumps blood through arteries, capillaries and veins providing oxygen and nutrients to the body's cells. Blood also carries away waste products.  

An adult human body contains approximately five liters of blood. Blood makes up about 7 or 8 percent of a person's body weight. About 2.75 to 3 liters of blood is plasma. The remaining portion is cellular.  

Plasma is the liquid portion of blood. The blood cells float in the plasma. Several other materials are dissolved in plasma including electrolytes, nutrients, vitamins, hormones, clotting factors, and proteins such as albumin and immunoglobulins. Plasma distributes these substances as it circulates throughout the body.  

In the cellular portion of blood we find red blood cells, white blood cells and platelets. The red blood cells carry oxygen from the lungs T white blood cells help to fight infection. Platelets are used to clot blood. All blood cells are produced in the bone marrow. When we are children, most of our bodies bones produce blood. As we age fewer bones are producing blood until blood is only produced by the bones of the spine, breastbone, ribs, pelvis and parts of the upper arm and leg.

The main difference between copying and moving is that the copying makes a duplicate of a file or directory in another location without affecting the original content while moving transfers the original file or directory to another location.
