True or 0
if code else code
public class ifElseExample {
public static void main(String[] args) {
statement statement int num=1;

if(num=1) {
System.out.println(“The Number is 1”);

} } Output:
The Number is 1

Java if-else-if ladder Statement
The if-else-if ladder statement executes one condition from multiple statements.
/* Java program to demonstrate if-else-if
//Syntax statement
if (condition_1) { It is a program to display a mark
} // code if condition_1 is true */
else if (condition_2) { public class ifElseifExample {
// code if condition_2 is true public static void main(String[] args) {
} int marks = 65;
else if (condition_3) {
// code if condition_3 is true if (marks <50) {
} System.out.println(‘Fail!”);
.. }
else { else if (marks >=50 && marks <60){
// code if all the conditions are false System.out.println(“D Grade”);
} }
