The if-else Java program uses if-else to execute statement(s) when a condition holds. The ability to change the behavior of a piece of code which is based on certain information in the environment is known as conditional code flow. The statement that goes in the if or else part of an if-else statement can be any kind of Java statement, including another if or if-else statement. This arrangement is nesting, and an if or if-else statement that includes another if or if-else statement is a nested if statement. The if/else statement executes a block of code if a specified condition is true. It tells your program to execute a certain section of code only if a particular test evaluates to true.For example, the Bicycle class could allow the brakes to decrease the bicycle's speed only if the bicycle is already in motion. Therefore, we can say that the switch statement is easy to modify and maintain. It is used for testing one condition from multiple statements. This just says "test if the user variable has a value of 50". In Java, the if-else-if ladder statement is used for testing conditions. The else statement is followed immediately after the closing braces of the if statement. In Java, the if-else-if ladder statement is used for testing conditions. Suppose we have multiple if-else in Java, then we use the decision making statement if-else if ladder.
