//定義整型one,two,three,并賦初值
int one = 10 ; int two = 20 ; int three = 0 ;?
//計算one+tow(也就是計算10+20），并賦值給three
three=one+two;?
//輸出three（也就是輸出10+20）
System.out.println("three=one+two==>"+three);?
//等同于three=three+one;就是將one+three重新賦給three（也就是30+10），并輸出three
three+=one; System.out.println("three+=one==>"+three);
//等同于three=three-one;就是將three-one重新賦給three（也就是20-10），并輸出three
?three-=one; System.out.println("three-=one==>"+three);
//等同于three=three*one;就是將three*one重新賦給three（也就是10*10），并輸出three
three*=one; System.out.println("three*=one==>"+three);

這個你哪一句看不懂，前面就是聲明變量，然后對每個變量進行不同的賦值運算符處理，打印出來
