以下实例使用了 String toUpperCase() 方法将字符串从小写转为大写:
- //StringToUpperCaseEmp.java 文件
- public class StringToUpperCaseEmp {
- public static void main(String[] args) {
- String str = "string abc touppercase ";
- String strUpper = str.toUpperCase();
- System.out.println("Original String: " + str);
- System.out.println("String changed to upper case: "
- + strUpper);
- }
- }
以上代码实例输出结果为:
- Original String: string abc touppercase
- String changed to upper case: STRING ABC TOUPPERCASE
