Java 破例

公共a类{
公共静态void main(字符串[]args){
扫描仪a=新的扫描仪(System.in);
int x;
x=a.nextInt();
if(x<5){
系统输出打印(“这是if语句”);
}else if(x我相信你指的是条件
而不是异常
,但是,你没有得到预期结果的原因是因为if语句的逻辑和优先级错误
if( x < 5) { // any input less than 5 will execute this if statement and will NOT proceed to the next blocks
System.out.print("This is if statement");
}else if(x<3){ // this is not reachable because the first if statement will catch all inputs less than 5 INCLUDING those less than 3
System.out.print("This is else if statement");
}else{
System.out.print("This is else statement");
}
什么异常?欢迎来到Stack Overflow!请看一看,并通读,特别是什么异常?如何不工作?您可能指的是条件
不是异常
,如果是,那是因为if语句的优先级错误
我建议您的名字要多想象一点。您有一个类a
和一个扫描器a
。一组x
元素,其中x
if( x < 3) { // this should come first
System.out.print("This is if statement");
}else if(x<5){
System.out.print("This is else if statement");
}else{
System.out.print("This is else statement");
}
