Explain with an example the if-else-if construct in java language?

Answer 1

The If else if construct is usually used when a series of conditions need to be validated or checked one by one.

Say for example you are writing a program to decide on projected weight of a person then you may need to have an if - else if block.

If height > 4 feet then

weight should be atleast 40 kgs

else if height > 5 feet then

weight should be atleast 50 kgs

else if height > 6 feet then

weight should be atleast 60 kgs

and so on...

Example code.

This method takes the height in inches as input and returns weight in kilograms as output.

public int getMinWeight(int height){

if(height > 4) {

return 40;

} else if(height > 5){

return 50;

} else if (height > 6){

return 60;

} else {

return 70;

}

}
