Give you an example of each type of Exception in Java through programs?

Answer 1

// A method which throws an exception.

// Declare an ArithmeticException to be thrown.

int integerDivision(int a, int b) throws ArithmeticException {

// If we try to divide by zero, throw our exception...

if(b == 0) {

throw new ArithmeticException("Division by 0");

}

// ...otherwise, return our result.

return a/b;

}

// A method which catches an exception.

void doSomeDivision() {

// Let's divide each integer [0,9] by one another...

for(int a = 0; a < 10; ++a) {

for(int b = 0; b < 10; ++b) {

// Try to do the division...

try {

final int q = integerDivision(a,b);

System.out.println(a + " / " + b + " = " + q);

} catch(ArithmeticException ex) {

// ...end up here in case of Exception

System.out.println("Cannot divide " + a + " by " + b);

}

}

}

}
