java循环方法 while,do while,for循环的示例分享

下文笔者通过示例的方式，讲述while,do while,for循环的示例分享，如下所示

while循环

public class Test {
   public static void main(String args[]) {
      int x = 8;
      while( x < 10 ) {
         System.out.print("x值 : " + x );
         x++;
         System.out.print("\n");
      }
   }
}

do…while 循环

public class Test {
   public static void main(String args[]){
      int x = 8;
 
      do{
         System.out.print("x 值: " + x );
         x++;
         System.out.print("\n");
      }while( x < 10 );
   }
}

for循环

public class Test {
   public static void main(String args[]) {
 
      for(int x = 8; x < 10; x = x+1) {
         System.out.print("x 值 : " + x );
         System.out.print("\n");
      }
   }
}
 

Java 增强for循环

public class Test {
   public static void main(String args[]){
      int [] numbers = {88,99,10,111,222};
      for(int x : numbers ){
         System.out.print( x );
         System.out.print(",");
      }
      System.out.print("\n");
      String [] names ={"java265", "java265.com", "java265.com-2", "java265.com-3"};
      for( String name : names ) {
         System.out.print( name );
         System.out.print(",");
      }
   }
}
