下面是一个使用逻辑运算符在if语句中判断多个条件的示例: java public class MultipleConditions { public static void main(String[] args) { int age = 25; boolean isEmployed = true; if (age >= 18 && isEmployed) { System.out.println("用户已成年且已就业"); } else if (age <...

publicclassMultipleConditions{publicstaticvoidmain(String[]args){inta=10;// 条件a的值intb=20;// 条件b的值intc=30;// 条件c的值if(a>b){// 当a大于b时System.out.println("条件a大于b");}elseif(b>c){// 当b大于c时System.out.println("条件b大于c");}else{// 当没有其他条件满足时Syste...
The if-else statement is the most basic way to control the flow of your code. It’s more verbose than the switch statement, but it can handle more complex conditions. Here’s an example: intnum=2;if(num==1){System.out.println('One');}elseif(num==2){System.out.println('Two');}...

Prior to Java SE 7, properly closing multiple resources quickly turned into a nightmare of nested if/try/catch/finally blocks that were often hard to write correctly. A folder is then a simple tree-based structure: Copy Copied to Clipboard Error: Could not Copy class Folder { private final...
