Java program to reverse a string using stacks - In this article, we will understand how to reverse a string using stacks. String is a datatype that contains one or more characters and is enclosed in double quotes(“”). The stack is a linear data struct
out.print("Enter a string :"); str= in.nextLine(); //get length of the input string int len= str.length(); //code to reverse string for ( int i = len- 1 ; i >= 0 ; i-- ) revStr= revStr+ str.charAt(i); //print reversed string System.out.println("Reverse String ...

先说下修复方式: "testStr".replace(newString( Character.toChars(x) ),"") 代码中的X对应错误中的code 值。 出现这种问题可以直接打印字符串的对应charCode , 方式: "testStr".charAt(4); // 0 然后根据code值执行相关替换就行了。 附上对应的ASCii 码:...

In the below code, we created a user-defined function LowerToUpper() that will accept a string and returns string having uppercase characters. To convert lowercase alphabets of the string to uppercase alphabets, we are extracting characters one by one from the string using String.ch...
