红色字就忽略吧，那是骚年想了半天没想出来的

public static void main(String [] args){
int x = 0;
while(x < 4){
System.out.print("a");//********0
if(x < 1){
System.out.print(" ");
}
System.out.print("n");
if(x < 1){
System.out.print("oise");
x = x - 1;
}
if(x == 1){
System.out.print("noys");
}
if(x > 1 ){
System.out.print(" oyster");
}
System.out.println("");
x = x + 2;
}
}

x = x + 2; 是啥意思？为啥不是x=x+1?

head first java？

有点像儿童编程
