In theory, you can have an unlimited level of nestings. But in practice, you should avoid nesting theif-elsestatement to make the code easier to understand. Here’s the syntax for using nestedif-elsestatements: if(condition1) {// Code to execute if the condition1 is trueif(condition2) ...
Important Note:Using code block is meant to use when you want to execute more than single statement. But we recommend to use code block even if you are using single statement because it comes in good programming practice. If Then Else: What if you want to execute some code if the if co...

一,1,编写程序,由键盘输入三个整数分别存入变量num1,num2,num3中,对它们进行排序,使用if-else结构,并按从小到大的顺序输出: packagepractice;importjava.util.Scanner;publicclassIfTest {publicstaticvoidmain( String args[]) { System.out.println("请输入第一个整数:"); Scanner scan=newScanner(System.in)...
else{ 执行表达式 1. } import java.util.Scanner; public class IfPractice { public static void main(String[] args) { // TODO Auto-generated method stub Scanner scan = new Scanner(System.in); System.out.println("请输入岳小鹏的成绩:"); ...

In this tutorial, we will learn how to determine whether the given input is an integer is or not.
"else if" statements? the depth of nesting "else if" statements is typically not limited by the programming languages themselves. however, it is considered a good practice to keep the nesting level as shallow as possible to maintain code readability and avoid unnecessary complexity. can i have ...
