public int indexOf(int ch) 它返回指定字符在String对象的位置。如下: 举例: “ab&&2″以&分割成”ab” “2” String tmp = “ab&&2”; String splitStr = null; int j = tmp.indexOf(“&”); // 找分隔符的位置 splitStr = tmp.substring(0, j); // 找到分隔符,截取子字符串 tmp = tmp....
String substring= str.substring(1); System.out.println(substring); 运行结果:raap-banner-top- 6)substring(int beginIndex, int endIndex) 从beginIndex开始,到endIndex结束截取字符串。包括start,不包括end String str ="graap-banner-top-"; String substring= str.substring(1,3); ...
public String repalce(char oldChar,char newChar);例如:String s = "the war of baronets".replace('r','y'); //s = "the way of bayonets"; 3|1010. 字符串大小写转换:public String toLowerCase(); 将字符串中的所有字符全部小写String s = "I Love Java".toLowerCase(); //s = "i ...
当时碰到这个问题直接想到两个方法,indexOf和replace,下面给出我的解决方法。 indexOf: String test = "..."; String str = ""; int ch = test.indexOf(""); test = test.substring(0, ch) + str + test.substring(ch, test.length())
