定义了两个字符串变量，目的在计算字符串的长度，并打印到屏幕上来。
编译的时候报错：


d:\java>javac Test.java
Test.java:8: cannot resolve symbol
symbol  : variable string
location: class Test
   i = string.length(Str1);
       ^
Test.java:9: cannot resolve symbol
symbol  : variable string
location: class Test
   j = string.length(Str2);
       ^
2 errors

代码如下：


public class Test {
   public static void main(String args[]) {
   String Str1;
   String Str2;
   int i,j;
   Str1 = "This is a string";
   Str2 = "welcome java study";
   i = string.length(Str1);
   j = string.length(Str2);
   System.out.println("Str1 Len" + i);
   System.out.println("Str2 Len" + j);
}
}
