java flow control statement

Java flow control statements: 1. if statement; 2. if-else statement; 3. if-else if-else statement; 4. switch statement; 5. while statement; 6. do-while statement; 7. for statement; 8. for-each loop; 9. break statement; 10. continue statement. Detailed introduction: 1. if statement, used to execute a code block based on specific conditions; 2. if-else statement, used to execute two different code blocks based on two conditions, etc.

What are the types of java flow control statements?

The operating system for this tutorial: Windows 10 system, DELL G3 computer.

Java flow control statements mainly include the following types:

1. if statement: is used to execute code blocks based on specific conditions.

if (condition) {  
    // code to execute if the condition is true  
}
Copy after login

2. if-else statement: is used to execute two different code blocks based on two conditions.

if (condition) {  
    // code to execute if the condition is true  
} else {  
    // code to execute if the condition is false  
}
Copy after login

3. if-else if-else statement: is used to execute multiple different code blocks based on multiple conditions.

if (condition1) {  
    // code to execute if condition1 is true  
} else if (condition2) {  
    // code to execute if condition2 is true  
} else {  
    // code to execute if neither condition1 nor condition2 is true  
}
Copy after login

4. Switch statement: is used to execute different code blocks based on different situations. Usually used in multiple selection situations, such as executing different blocks of code based on the value of a variable.

switch (variable) {  
    case value1:  
        // code to execute if variable equals value1  
        break;  
    case value2:  
        // code to execute if variable equals value2  
        break;  
    default:  
        // code to execute if variable does not match any value in the switch statement  
}
Copy after login

5. While statement: is used to repeatedly execute a piece of code until the specified condition is no longer met.

while (condition) {  
    // code to execute repeatedly until the condition becomes false  
}
Copy after login

6. do-while statement: Similar to the while statement, but the code block will be executed at least once and then the condition will be checked. If the condition is true, execution of the code block continues.

do {  
    // code to execute at least once, then repeatedly if the condition is true  
} while (condition);
Copy after login

7. for statement: is used to repeatedly execute a piece of code a specified number of times. It consists of three basic parts: initialization, conditions and subsequent operations.

for (initialization; condition; update) {  
    // code to execute repeatedly until the condition becomes false  
}
Copy after login

8. for-each loop (enhanced for loop): Used to traverse the elements in an array or collection. It does not need to know the size of the collection, but automatically handles indexing and iteration of elements.

for (element : collection) {  
    // code to execute for each element in the collection  
}
Copy after login

9. Break statement: is used to jump out of the current loop or switch statement immediately. It can be used with loops or switch statements to exit early when certain conditions are met.

10. Continue statement: is used to skip the remaining part of the current loop and start the next iteration. It can be used with loops to skip the current iteration when certain conditions are met.

Break or return from Java 8 stream forEach? Break or return from Java 8 stream forEach? Feb 07, 2025 pm 12:09 PM

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

Java Program to Find the Volume of Capsule Java Program to Find the Volume of Capsule Feb 07, 2025 am 11:37 AM

Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods. Capsule volume formula The formula for capsule volume is as follows: Capsule volume = Cylindrical volume Volume Two hemisphere volume in, r: The radius of the hemisphere. h: The height of the cylinder (excluding the hemisphere). Example 1 enter Radius = 5 units Height = 10 units Output Volume = 1570.8 cubic units explain Calculate volume using formula: Volume = π × r2 × h (4
