• Decision Control Structure

  Java statements that allows us to select and execute specific blocks of code while skipping other sections.
• if-statement specifies that a statement (or block of code) will be executed if and only if a certain boolean statement is true.
• The if-statement has the form, where, boolean expression is either a boolean expression or boolean variable.
• The if-statement has the form, where, boolean expression is either a boolean expression or boolean variable.
• The boolean_expression part of a statement should evaluate to a boolean value. That means that the execution of the condition should either result to a value of true or false
• The boolean_expression part of a statement should evaluate to a boolean value. That means that the execution of the condition should either result to a value of true or false
• if-else statement is used when we want to execute a certain statement if a condition is true, and a different statement if the condition is false
• switch statement has been matched, all the statements associated with that case are executed. Not only that, the statements associated with the succeeding cases are also executed.
• To prevent the program from executing statements in the subsequent cases, we use a break statement as our last statement
