CONTROL STATEMENTS IN JAVA.
If statement:
if statement is the most basic of all the control statements. It tells your program to execute a certain section of code only if a particular test evaluates to true. An if statement consists of a boolean expression followed by one or more statements.
Syntax:
if (Boolean-expression) {
statement;
}
If-else statement:
An if statement can be followed by an optional else statement, which executes when the boolean expression is false.
Syntax:
If (Boolean-expression) {
Statement;
}
else {
statement;
}
Switch statement:
A switch statement allows a variable to tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each case.
Syntax:
switch(expression){
case constant-expression :
Statement(s);
break;
case constant-expression :
Statement(s);
break;
default:
statements;}
for loop
A for loop is a repetition control structure that allow you to efficiently write a loop that needs to execute a specific number of times.
Syntax:
}
while Loop :
while loop executes a statement repeatedly, until the value of condition becomes false. The test takes place before each iteration.while loop executes a statement repeatedly, until the value of condition becomes false. The test takes place before each iteration.
Syntax:
while(Expression){
Statement(s);
}
do-while Loop :
Unlike for and while loops, which test the loop condition at the top of the loop, the do..while loop checks the condition at the bottom of the loop.
A do..while loop is similar to the while loop, except that a do..while loop is guaranteed to execute at least one timeUnlike for and while loops, which test the loop condition at the top of the loop, the do..while loop checks the condition at the bottom of the loop.A do..while loop is similar to the while loop, except that a do..while loop is guaranteed to execute at least one time
