用 for break報錯
public?static?void?main(String[]?args)?{
????????int?score?=?53;?
????????int?count?=?0;
????????System.out.println("加分前成績"+score);?
????????for(;score<=60;score++){
????????????count=count+1;
????????????if(score>=60){
????????????????break;
????????????????System.out.println(count);
????????????}
????????}??
????}System.out.println(count);報錯。。為什么啊

因為執行了break;以后就會跳出循環，下面那句打印輸出就肯定不會被執行，所以被編譯器認為是多余的。把這句打印輸出和break;上下調換一下位置就行了。

輸出語句放到for外面

怎么沒有main語句啊

把System.out.println(count);放到if外面去

public?static?void?main(String[]?args)?{
????????int?score?=?53;?
????????int?count?=?0;
????????System.out.println("加分前成績"+score);?
????????for(;score<=60;score++){
????????????count=count+1;
????????????if(score>=60){
????????????????break;
????????????}
????????}??
????????????????System.out.println(count);
????}
?????????把下面一段改成這樣試試
