Write a Java program to move all lower case letters to the front of a given word. This will keep the relative position of all the letters (both upper and lower case) same. Sample Solution-1: Java Code: publicclasstest{publicstaticvoidmain(String[]args){Stringtext="Java";System.out.print...
java.io包包含一个“PrintStream”类,该类有两种格式方法,可以用来替换“print”和“println”。这些方法“format”和“printf”彼此等效。熟悉的“系统”。out”恰好是“PrintStream”对象,因此您可以在“System.out”上调用“PrintStream”方法。因此,您可以在代码中以前使用过“print”或“println”的任何地方使用“for...
