Control Statements - Decision Making | OOP using JAVA | SNS Institutions

#snsinstitutions #snsdesignthinkers #designthinking In Java, decision-making control statements are used to determine the flow of execution based on certain conditions. They allow a program to make choices and execute different code blocks depending on whether conditions evaluate to true or false. The most basic form is the if statement, which executes a block only if the specified condition is true. When there are two possible outcomes, the if-else statement is used, where one block runs if the condition is true and another if it is false. For scenarios requiring multiple condition checks, Java provides the if-else-if ladder, which evaluates conditions in sequence until one is found to be true. If no conditions are met, the final else block executes. Another form is the nested if, where an if statement is placed inside another if block, allowing more granular decision-making. Java also offers the switch statement for cases where a single variable or expression needs to be compared against multiple possible values. Each case in a switch statement contains code to execute when the case matches, and the break keyword prevents fall-through to other cases. If no cases match, the default case runs. The choice between if and switch depends on the nature of the condition: if is better for complex logical expressions, while switch is ideal for discrete values like integers, strings, or enums. These decision-making statements are fundamental to creating dynamic, responsive, and logical Java programs, as they give developers precise control over which parts of code execute in different situations.
