String的startswith方法检查字符串是否以特定的前缀开头。
它返回布尔数据类型。
方法签名:
public boolean startsWith(String prefix)
String startstwith示例:
package org.igi.theitroad; public class StringStartsWithExample { public static void main(String[] args) { String str = "theitroad"; if (str.startsWith("java")) { System.out.println("String starts with java"); } else { System.out.println("String does not start with java"); } if (str.startsWith("JAVA")) { System.out.println("String starts with JAVA"); } else { System.out.println("String does not start with JAVA"); } } }
运行上面的程序时,我们将得到以下输出:
String starts with java String does not start with JAVA
请注意startsWith方法是区分大小写的,如上面的示例所示
