擬似コード

ようやく progJ.pdf 「１．簡単な例」の初稿ができました．

補足：(1) P11.java
public class P11{
  public static void main(String[ ] args){
    int i=2, k=3;
    System.out.println("i+k="+(i+k));
    //
    int[] m1, n1={0,1,2}; int[][] m2, n2={new int[2], new int[3]};
    m1 = new int[3]; n2[1][2] = 4;
    m2 = new int[2][]; m2[1] = new int[3];
    String s = "abc"; System.out.println(n2[1][2]+","+s);
  }
}
(2) P15.java
public class P15{
  static void add(int[] p, int k){p[0] += k;}
  public static void main(String[ ] args){
    int[] n={2,3};
    add(n, 4); System.out.println(n[0]);
  }
}
(3) P17.java
import java.io.*;
public class P17{
  public static void main(String[ ] args) throws IOException{
    BufferedReader r; String s; StringBuffer b = null;
    try{
      r = new BufferedReader(new InputStreamReader(System.in));
      s = r.readLine(); b = new StringBuffer(s);
    }catch(IOException e){System.out.println(e);}
    System.out.println("b="+b);
  }
}
