Java Program to check two strings are Anagram or not

An anagram of a string is another string that contains same characters, only the order of characters can be different. For example, “LISTEN” and “SILENT” are anagram of each other.



package com.caots.test;

import java.util.Arrays;

public class Test {
public static void main(String[] args) {
//String s1="LISTEN", s2="SILENT";
String s3="TRIANGLE", s4="INTEGRAL";
boolean flag=checkAnagram(s3, s4);
if(flag==true)
System.out.println(s3+" & "+s4+" are Anagram strings");
else
System.out.println("No Anagram strings");
}

public static boolean checkAnagram(String s1,String s2){
char[] crr1=s1.toCharArray();
char[] crr2=s2.toCharArray();
Arrays.sort(crr1);
Arrays.sort(crr2);
if(Arrays.equals(crr1, crr2))
return true;
return false;
}
}

How to create a pyramid of numbers in java?

package com.npp.test;

public class Test {

public static void main(String[] args) {

int n=10;
for(int i=1;i<=n;i++)
for(int j=1;j<=n+1;j++)
System.out.print(i>9?j<=n-i+1?"  ":i+"  ":j<=n-i+1?"  ":i+"   ");
}
  System.out.println();
}



  Instead of writing ternery operator we can write this also

if(i>9)
    System.out.print(j<=n-i+1?"  ":i+"  ");
else
    System.out.print(j<=n-i+1?"  ":i+"   ");
