} the else { 
	System.out.println ( "fail"); 
}

failed

3. if ... else if ... else  conditions judgment

if (Boolean expression 1) { 
   // If the Boolean expression is true of the execution of the code 1 
} else if (Boolean expression 2) { 
   // If the Boolean expression is true of the execution of the code 2 
} else if (Boolean expression formula 3) { 
   // If the boolean expression evaluates to true execution code 3 
} the else { 
   // If the above boolean expression is true not execute code 
}

int score = 88;
 
if(score > 90){
	System.out.println("优秀");
}else if(score > 80){
	System.out.println("良好");
}else if(score > 60){
