一、print 通过System.out.print方法调用,print方法的参数有很多种:boolean、char、char[]、String、int、float、double、long等。 print的输出末尾不换行。 1、print(boolean b) 打印boolean类型时,输出只有true和false两种。我们查看print(boolean b)的源代码,可以看到: 当b为true时输出true,为false输出false。这很...
inti =1;charc ='f';doubled =3.14;//coutcout<< i <<endl;cout<< c <<endl;cout<< d <<endl;//printfprintf("%d\n%c\n%f", i, c, d); 传统C中的printf 函数,虽然也能达成不定个数的形参的调用,但其并非类别安全,写输出格式也不方便,而且支持的是基础类型。使用cout缺点在于代码量会比较...

d指按实际长度，以带符号十进制整数形式进行输出，%8.6f指以浮点小数（包括单精度和双精度）进行输出，输出结果占8格，取小数点前6位小数。d格式：用来输出十进制整数。有以下几种用法: 1、%d：按整型数据的实际长度输出。2、%md：m为指定的输出字段的宽度。如果数据的位数小于m，则左端补以...

只有一个区别：print在本次输出之后不会换行，println在本次输出之后会换行。两者区别及用法实例演示如下：一、实例代码如下。二、执行结果如下：可以看到println相当于是print加上换行符的效果。三、执行99乘法表中两者使用的区别，示例代码如下。四、执行结果如下。
