Can you explain the following concepts in Java in plain word and provide a easy-to-understand example code to illustrateProgram control flowA Sequence structureB Selection structureC Repetition struc

Program control flow refers to the order in which instructions in a program are executed.

A. Sequence structure is the default structure in programming, where the instructions are executed one after the other in a sequence.

Example:

int num1 = 5;
int num2 = 10;
int sum = num1 + num2;
System.out.println("The sum is " + sum);

In this example, the instructions are executed in sequence - first, the value of num1 is assigned to 5, then the value of num2 is assigned to 10, then the sum of num1 and num2 is calculated and stored in sum, and finally the message "The sum is" along with the value of sum is printed to the console.

B. Selection structure allows a program to make a decision based on a condition. It consists of an if statement that checks the condition, and executes a block of code if the condition is true.

Example:

int num = 10;
if(num > 5){
    System.out.println("The number is greater than 5");
}

In this example, the program checks if num is greater than 5 using the if statement. Since the condition is true, the message "The number is greater than 5" is printed to the console.

C. Repetition structure allows a program to repeat a block of code multiple times based on a condition. It consists of a loop that executes the block of code as long as the condition is true.

Example:

int i = 1;
while(i <= 5){
    System.out.println(i);
    i++;
}

In this example, the program uses a while loop to print the numbers from 1 to 5 to the console. The loop executes as long as the value of i is less than or equal to 5. The value of i is incremented by 1 in each iteration of the loop.

D. Jump (Sequence) structure allows a program to transfer control to a different part of the program. It consists of statements like break and continue that can be used to interrupt the normal flow of the program.

Example:

for(int i = 1; i <= 10; i++){
    if(i == 5){
        break;
    }
    System.out.println(i);
}

In this example, the program uses the break statement to exit the loop when the value of i is equal to 5. This interrupts the normal flow of the program and transfers control to the next statement after the loop. The numbers from 1 to 4 are printed to the console before the loop is interrupted.
