What are the static precision positioning statements?

Static precision positioning statements include: 1. Conditional statements, used to execute specific code blocks when specific conditions are met; 2. Loop statements, used to repeatedly execute a block of code, and for loops are used to follow specified The code block is repeatedly executed a number of times, and the while loop is used to repeatedly execute the code block when the specified conditions are met; 3. The exception handling statement is used to capture and handle exceptions that may occur in the code, and the try-catch statement is used to capture code that may cause exceptions. block and perform corresponding processing when an exception occurs. The throw statement is used to manually raise exceptions and so on.

Static precision positioning statement refers to the syntax structure used in programming to ensure the accuracy and predictability of the code. The following are some common static precision positioning statements:

1. Conditional statement (if statement):

The if statement is used to execute specific code when specific conditions are met. piece. Its basic structure is: if (condition) {code block}. For example:

if (x > 5) {
    print("x大于5");
}

2. Loop statement:

Loop statement is used to repeatedly execute a block of code until the specified condition is met. Common loop statements include for loop and while loop.

For loop: The for loop is used to repeatedly execute a block of code a specified number of times. Its basic structure is: for (initialization; condition; update) {code block}. For example:

for (int i = 0; i < 5; i++) {
    print(i);
}

while loop: while loop is used to repeatedly execute a block of code when a specified condition is met. Its basic structure is: while (condition) {code block}. For example:

while (x < 10) {
    x++;
}

3. Exception handling statements:

Exception handling statements are used to capture and handle exceptions that may occur in the code. Common exception handling statements include try-catch statements and throw statements.

try-catch statement: The try-catch statement is used to capture code blocks that may cause exceptions and perform corresponding processing when the exception occurs. Its basic structure is:

try {
    // 可能引发异常的代码块
} catch (Exception e) {
    // 异常处理代码
}

throw statement: The throw statement is used to manually raise exceptions. Its basic structure is: throw exception object. For example:

if (x < 0) {
    throw new IllegalArgumentException("x不能为负数");
}

These are some common static precision positioning statements that can help you ensure the accuracy and predictability of your code in programming. Please choose the appropriate statement based on your specific needs and apply it to your code.
