Branching Statements
If statement:
Use if statement to specify a block of code to be executed, if a specified condition is true.
Syntax:
if(condition)
{
//code to be executed
}
Program:
public class ifstatement1
{
public static void main(String[]args)
{
if(10>5)
{
System.out.println("10 is Greater then");
}
}
}
Output:
10 is Greater then
else statement:
Use the else statement to specify a block of code to be executed ,if the condition is false.
Syntax:
if(condition)
{
//code to be executed
}
else
{
//code to be executed
}
Program:
public class ifstatement1
{
public static void main(String[]args)
{
int time=12;
if(time<10)
{
System.out.println("12pm is afternoon ");
}
else
{
System.out.println("10am is morning");
}
}
}
Output:
10am is morning
else if statement:
Use else if statement to specify a new condition ,if the first condition is false.
Syntax:
if(condition)
{
//code to be executed
}
elseif
{
//code to be executed
}
else
{
//code to be executed
}
Program:
public class num
{
public static void main(String[] args)
{
int i = 20;
if (i == 10)
{
System.out.println("i is 10\n");
}
else if (i == 15)
{
System.out.println("i is 15\n");
}
else if (i == 20)
{
System.out.println("i is 20\n");
}
else
{
System.out.println("i is not present\n");
System.out.println("Outside if-else-if");
}
}
}
Output:
i is 20
Nested if statements:
Nested if statement is a set of if condition one within another. The inner if conditions are only executed when the outer if condition is true ,otherwise the else block is executed.
Syntax:
if(condition 1)
{
if (condition 2)
{
True block of statement 1;
}
}
else
{
false block of condition 1;
}
