Java Exchange two variable values without a temporary variable

• Exchange values for two variables, not for temporary variables

  1  Public class test{2      Public Static void Main (string[] args) {3         int a = 1; 4         int b = 2; 5         // Please exchange the values of two variables 6     }  7 }    

  exchanging values for two variables
• Add and subtract to achieve exchange

  1  Public classtest{2      Public Static voidMain (string[] args) {3         intA = 1;4         intb = 2;5         //Please exchange the values of two variables6a=a+b;7b=a–b;8A=a–b;9     }  Ten}

  exchange of variable values by adding and subtraction
• Different or realized exchange

  1  Public classtest{2      Public Static voidMain (string[] args) {3         intA = 1;4         intb = 2;5         //Please exchange the values of two variables6a^=b;7b^=A;8a^=b;9     }  Ten}

  swapping using XOR operations
