String str = "Hello"; int length = str.length(); System.out.println("Length of the string is: " + length); 复制代码 如果不将String.length()方法的返回值赋给一个变量或者直接打印输出,而是单独使用该方法,会导致编译错误。例如: String str = "H

java中数组是没有length()方法的,只有length属性,数组array.length返回的是该数组的长度。字符串String是有length()方法的,str.length()返回的是该字符串的长度。
下面是一个示例代码,演示了如何测试Java中方法参数的限制: publicclassStringParameterLimit{publicstaticvoidmain(String[]args){StringlongString=generateLongString();System.out.println("String length: "+longString.length());testMethod(longString);}publicstaticvoidtestMethod(Stringparam){System.out.println("...

limiting the maximum size of the generated Java Virtual Machine code for any method, instance initialization method, or static initializer (the size of any code array) to 65534 bytes 如果方法的Java虚拟机代码恰好是65535字节长,并且以一条1字节长的指令结束,那么该指令就不能被异常处理程序保护。编译器...
The length() method returns the length of a given string. The length is equal to the number of characters (code units) in the string. Example: Java String length() class Main { public static void main(String[] args) { String str1 = "Java"; String str2 = ""; System.out.println(...
