Conditional Statements in Java

    Conditions are used to control the flow of a program based on certain criteria. The most common way to express conditions is through the use of 'if', 'else if', and 'else' statements. Additionally, Java provides the switch statement for multi-branch conditions.

• if Statement

int number = 10;

if (number > 0) {

System.out.println("Number is positive");

}

• if-else Statement

int number = -5;

if (number > 0) {

System.out.println("Number is positive");

} else {

System.out.println("Number is non-positive");

}

• if-else if-else Statement

int number = 0;

if (number > 0) {

System.out.println("Number is positive");

} else if (number < 0) {

System.out.println("Number is negative");

} else {

System.out.println("Number is zero");

}

• Switch Statement

char grade = 'B';

switch (grade) {

case 'A':

System.out.println("Excellent");

break;

case 'B':

System.out.println("Good");

break;

case 'C':

System.out.println("Average");

break;

default:

System.out.println("Invalid grade");

}
