查询词典 variable-density system

For example, the following statement is correct: System.out.println(x = 1); which is equivalent to x = 1; System.out.println; The following statement is also correct: i = j = k = 1; which is equivalent to k = 1; j = k; i = j; In an assignment statement, the data type of the variable on the left must be compatible with the data type of the value on the right.

例如，以下声明是正确的： 55 System.out.println （十= 1 ）；这相当于为x = 1 ； 55 System.out.println ；以下声明也是正确的：= j =当K = 1 ；这相当于当K = 1 ； j =钾；=焦耳；在转让的声明中，数据类型的变量在左边则必须与数据类型的价值，对正确的。
