1.if条件语句 常见问题与易错点: 忘记大括号:单行if语句如果没有使用大括号,只会影响该行,可能导致逻辑错误。例如: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 if(condition)statement; 如果你想让多行代码块受if控制,记得加上大括号: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 if(condition...

5. Using Ternary Operator to Replace Simpleif-else We can also use theternary operatorinstead of a simpleif-elsestatement to make the code more concise and readable. Consider a simpleif-elsestatement that checks if a number is greater than or less than a value, and stores the value in a...
Using the example above to check the age of the user, the If-Else statement would be constructed like this: Public static void main(String[ ] args) { Int userAge = 18; If (userAge <= 18) { System.out.println(“User is 18 or younger”); ...
