Here is a comprehensive response on controlling statements in Java with examples:

Control Statements in Java

Control statements are used to control the flow of program execution. They determine which part of the code should be executed based on certain conditions. In this response, we will cover several types of control statements in Java.

1. If-Else Statement

The if-else statement is used to execute a block of code if a specified condition is true. If the condition is false, an alternative block of code can be executed.

Example:

int x = 10;
if (x > 5) {
System.out.println("x is greater than 5");
} else {
System.out.println("x is less than or equal to 5");
}

Output: x is greater than 5

2. If-Else-If Statement

The if-else-if statement is used to execute a block of code if multiple conditions are true.

Example:

int x = 15;
if (x > 10) {
System.out.println("x is greater than 10");
} else if (x == 10) {
System.out.println("x is equal to 10");
} else {
System.out.println("x is less than 10");
}

Output: x is greater than 10

3. Switch Statement

The switch statement is used to execute a block of code based on the value of an expression.

Example:

int day = 4;
switch (day) {
case 1:
System.out.println("Monday");
break;
case 2:
System.out.println("Tuesday");
break;
case 3:
System.out.println("Wednesday");
break;
default:
System.out.println("Invalid day");
}

Output: Wednesday

4. Loops (For, While, Do-While)

Loops are used to execute a block of code repeatedly for a specified number of times or until a certain condition is met.

Example:

for (int i = 0; i < 5; i++) {
System.out.println("Loop " + i);
}

Output:

Loop 0
Loop 1
Loop 2
Loop 3
Loop 4

Conclusion

In this response, we have covered several types of control statements in Java: if-else, if-else-if, switch, and loops. These statements help control the flow of program execution based on certain conditions or expressions.
