循环判断的问题

shijies 2018-03-10 10:39:24

以下代码可以编译通过，但是还是有问题，请赐教。
package com.test;

public class test {

public static void main(String[] args) {
String text1="Beijing Shanghai Nanjing Guangzhou";

String text2=text1.trim();
StringBuilder strBuilder = new StringBuilder();

for (int i = 0; i < text2.length(); i++) {
char charAt = text2.charAt(i);
if (charAt != ' ')
strBuilder.append(charAt);

else if ( (charAt == ' ') || (strBuilder.length() != 0))
{

System.out.println(strBuilder.toString());
strBuilder.delete(0, i);

}
else if( (charAt == ' ') || (strBuilder.length() == 0))
continue;
}
}
}

这样一改就向着正确的方向前进了一大步，但是最后一个字符串（Guangzhou）还是没有打印出来。 package com.test; public class test { public static void main(String[] args) { String text1="Beijing Shanghai Nanjing Guangzhou"; String text2=text1.trim(); StringBuilder strBuilder = new StringBuilder(); for (int i = 0; i < text2.length(); i++) { char charAt = text2.charAt(i); if (charAt != ' ') strBuilder.append(charAt); else if ( (charAt == ' ') && (strBuilder.length() != 0)) { System.out.println(strBuilder.toString()); strBuilder.delete(0, i); } else if( (charAt == ' ') && (strBuilder.length() == 0)) continue; } } }

		}
		if ((strBuilder.length() != 0))
			System.out.println(strBuilder.toString());
