Java - Decision Making statements

Java - Decision Making Statements

  • Conditional operations are enabled in java programs through its relational and logical operators. 
  • Thus a conditional expression is evaluated and a Boolean literal value, true or false is returned. 
  • Code execution flow is based on this value and hence such conditional expressions are termed as Decision Making Statements.
  • Two types of decision making statements are available in Java:
    • If Statement
    • Switch case Statement

If Statements :

  • Executes a single or a block of statements based on the Boolean condition present near the keyword “if”.

Switch Case Statement :

  • Tests an expression of type char, byte, short, or int against a set of values. 
  • Based on the matching value, a case branch is selected and executed. 
  • If none of the value matches, then the default case statements are executed as shown below:
