Java examples: Switch Statement
public static void witchStatment(int num) { | |
System.out.println("\nEXAMPLE: Switch Statement"); | |
switch(num){ //Check the value | |
case 0: | |
System.out.println("Case = " + num); // Execute this if 'case' matches the 'value' | |
break; // Stop the statement | |
case 1: | |
System.out.println("Case = " + num); // Execute this if 'case' matches the 'value' | |
break; // Stop the statement | |
case 2: | |
System.out.println("Case = " + num); // Execute this if 'case' matches the 'value' | |
break; // Stop the statement | |
case 3: | |
System.out.println("Case = " + num); // Execute this if 'case' matches the 'value' | |
break; // Stop the statement | |
case 4: | |
System.out.println("Case = " + num); // Execute this if 'case' matches the 'value' | |
break; // Stop the statement | |
default: | |
System.out.println("Default = " + num); | |

Java examples: While Loop vs ‘do’-while loop
While Loop
public static void whileLoop(){ | |
System.out.println("\nEXAMPLE: While Loop"); | |
int num = 0; | |
while(num <= 20) { // Check the while condition first, Then execute the loop | |
// Then while 'l' is less than or equal to '0' | |
System.out.println("num = " + num); | |
num++; //increment 'l' by 1 | |
} | |
} | |
‘do’-while loop
public static void doWhileLoop() { | |
System.out.println("\nEXAMPLE: Do While Loop"); | |
int num = 0; | |
do { | |
// DO the work... Execute the loop first | |
System.out.println("num = " + num); | |
num++; //increment 'l' by 1 | |
} while(num <= 20); // Check the conditions | |
} |
