Java Basic(18)-Nested if Statements

class apples{

public static void main(String args[]){

int age = 80;

if(age<50){ → 如果該值小於50

System.out.println("You are young"); → 將運行此statement

}else{

System.out.println("You are old"); → 但如果不是

if (age>75){ → 值大於75

System.out.println("You are REALLY OLD"); → 將運行此statement

}else{ → 但如果不是

System.out.println("You are not really that old"); → 運行此statement

}

}

}

}

運行這個程序，你會看到：

You are old

You are REALLY OLD
