头歌java实训作业答案控制语句

以下是头歌Java实训作业中可能涉及到的控制语句的一些示例：

1. if语句：

int x = 10;
if (x > 5) {
    System.out.println("x is greater than 5");
}

2. if-else语句：

int x = 10;
if (x > 15) {
    System.out.println("x is greater than 15");
} else {
    System.out.println("x is less than or equal to 15");
}

3. switch语句：

int day = 4;
switch (day) {
    case 1:
        System.out.println("Monday");
        break;
    case 2:
        System.out.println("Tuesday");
        break;
    case 3:
        System.out.println("Wednesday");
        break;
    case 4:
        System.out.println("Thursday");
        break;
    case 5:
        System.out.println("Friday");
        break;
    default:
        System.out.println("Weekend");
}

4. for循环：

for (int i = 0; i < 10; i++) {
    System.out.println(i);
}

5. while循环：

int i = 0;
while (i < 10) {
    System.out.println(i);
    i++;
}

6. do-while循环：

int i = 0;
do {
    System.out.println(i);
    i++;
} while (i < 10);
