Java，包括打印行中的int变量 你如何在这个句子的中间插入一个变量 System.out.println("Since there are (trying to insert int bluerocks here) there must be less than 12 normal rocks "+bluerocks);

您可以通过几种方式实现这一点，Java支持内联字符串连接，因此这是有效的：

System.out.println("Since there are " + bluerocks + " there must be less than 12 normal rocks  ");

或者，您可以使用格式化方法：

你可以像这样使用

或者，像

---

你有一些选择

或者使用字符串连接，就在您想要的位置，注意引号的数量：

System.out.println("Since there are (" + bluerocks
                    + ") there must be less than 12 normal rocks");

…或通过printf替换符号：

---

这里的许多人都给了你正确的答案

System.out.println("Since there are " + bluerocks + " there must be less than 12 normal rocks");

或

或

但是，如果这看起来很复杂或困难，那么你可以将其分解为多个打印语句

System.out.print("Since there are ");
System.out.print(bluerocks);
System.out.print(" there must be less than 12 normal rocks\n");

这都是关于学习的，不需要在这里大惊小怪。

System.out.println因为有+蓝岩+必须少于12个普通岩；或者看String.formatLook.只需拆分字符串。或者使用格式字符串。

System.out.println("Since there are (" + bluerocks
                    + ") there must be less than 12 normal rocks");

System.out.printf("Since there are (%d) there must be less than 12 normal rocks",
                  bluerocks);

System.out.println("Since there are " + bluerocks + " there must be less than 12 normal rocks");

System.out.format("Since there are %d there must be less than 12 normal rocks  \n", bluerocks);

System.out.printf("Since there are %d there must be than 12 normal rocks%n", bluerocks);

System.out.print("Since there are ");
System.out.print(bluerocks);
System.out.print(" there must be less than 12 normal rocks\n");
