Nested if
Q.1 ] what is nested if and their programming example?
· A nested if is an if statement in which we can use other if statements many number times.
Example1:
class
Example1 {
public static void
main(String args[]) {
int a=10;
if (a>5) {
if (a>9) {
System.out.println(“the
value is grater than 9”);
}
else
{
System.out.println(“the
value is lower than 9”);
}
}
Example2:
class
Example2 {
public static void
main(String args[]) {
int a=20,
b=50, c=100 ;
if (a>15) {
if (a>40) {
if (a>120) {
System.out.println(“the
value is grater than 120”);
}
else
{
System.out.println(“the
value is lower than 120”);
}
}
·
If – else
if the leader
·
It is a common programming syntax contract that is based on the
sequence if nested if.
Example:
if (condition 1) {
statement; \\ executing condition 1 then return true
}
else if (condition 2) {
statement; \\ executing condition 2 then return true
}
else (condition 3) {
statement; // when no other condition is satisfied
}
Q1] What is the basic
structure of if and else if?
if (condition 1) {
statement; \\ executing condition 1 then return true
}
else if (condition 2) {
statement; \\ executing condition 2 then return true
}
else if (condition 3) {
statement; \\ executing condition 2 then return true
}
else (condition 4) {
statement; // when no other condition is satisfied
}
Q.4 ] write a java
program which will tell that the given
number is between range 20- 50 or not?
class Range
{
public static void
main(String args[]) {
int a=26;
if (a>15) {
if (a<38) {
System.out.println(“the
value is one range
” + a);
}
else if (a == 50) {
System.out.println(“the
value is range ” + a);
}
else
{
System.out.println(“the
value is getter than 40” +a);
}
else
{
System.out.println(“the
value is lower than 40”+a);
}
}
}
