Decision control structures are Java statements that allows us to select and execute specific blocks of code while skipping other sections.
if statement
The 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,
if( boolean_expression )
statement;
or
if( boolean_expression ){
statement1;
statement2;
. . .
}
where, boolean_expression is either a boolean expression or boolean variable.
For example, given the code snippet,
int grade = 68;
if( grade > 60 ) System.out.println("Congratulations!");
or
int grade = 68;
if( grade > 60 ){
System.out.println("Congratulations!");
System.out.println("You passed!");
}
